# Rust's standard distribution of crates and tools
|
|
|
|
|
#
|
|
|
|
|
# The crates outlined below are the standard distribution of libraries provided
|
|
|
|
|
# in a rust installation. These rules are meant to abstract over the
|
|
|
|
|
# dependencies (both native and rust) of crates and basically generate all the
|
|
|
|
|
# necessary makefile rules necessary to build everything.
|
|
|
|
|
#
|
|
|
|
|
# Here's an explanation of the variables below
|
|
|
|
|
#
|
|
|
|
|
# TARGET_CRATES
|
|
|
|
|
# This list of crates will be built for all targets, including
|
|
|
|
|
# cross-compiled targets
|
|
|
|
|
#
|
|
|
|
|
# HOST_CRATES
|
|
|
|
|
# This list of crates will be compiled for only host targets. Note that
|
|
|
|
|
# this set is explicitly *not* a subset of TARGET_CRATES, but rather it is
|
|
|
|
|
# a disjoint set. Nothing in the TARGET_CRATES set can depend on crates in
|
|
|
|
|
# the HOST_CRATES set, but the HOST_CRATES set can depend on target
|
|
|
|
|
# crates.
|
|
|
|
|
#
|
|
|
|
|
# TOOLS
|
|
|
|
|
# A list of all tools which will be built as part of the compilation
|
|
|
|
|
# process. It is currently assumed that most tools are built through
|
|
|
|
|
# src/driver/driver.rs with a particular configuration (there's a
|
|
|
|
|
# corresponding library providing the implementation)
|
|
|
|
|
#
|
|
|
|
|
# DEPS_<crate>
|
|

# These lists are the dependencies of the <crate> that is to be built.

# Rust dependencies are listed bare (i.e. std) and native
|
2014-05-03 00:56:35 +00:00

# dependencies have a "native:" prefix (i.e. native:hoedown). All deps
|
2014-01-25 03:27:22 +00:00
|
|
|
# will be built before the crate itself is built.
|
|
|

|
#
|
|
|
|
|
# TOOL_DEPS_<tool>/TOOL_SOURCE_<tool>
|
|
|

|
# Similar to the DEPS variable, this is the library crate dependencies
|
|
|
|
|
# list for tool as well as the source file for the specified tool
|
|
|
|
|
#
|
|
|
|

# You shouldn't need to modify much other than these variables. Crates are
|

Add libunicode; move unicode functions from core
- created new crate, libunicode, below libstd
- split Char trait into Char (libcore) and UnicodeChar (libunicode)
- Unicode-aware functions now live in libunicode
- is_alphabetic, is_XID_start, is_XID_continue, is_lowercase,
is_uppercase, is_whitespace, is_alphanumeric, is_control,
is_digit, to_uppercase, to_lowercase
- added width method in UnicodeChar trait
- determines printed width of character in columns, or None if it is
a non-NULL control character
- takes a boolean argument indicating whether the present context is
CJK or not (characters with 'A'mbiguous widths are double-wide in
CJK contexts, single-wide otherwise)
- split StrSlice into StrSlice (libcore) and UnicodeStrSlice
(libunicode)
- functionality formerly in StrSlice that relied upon Unicode
functionality from Char is now in UnicodeStrSlice
- words, is_whitespace, is_alphanumeric, trim, trim_left, trim_right
- also moved Words type alias into libunicode because words method is
in UnicodeStrSlice
- unified Unicode tables from libcollections, libcore, and libregex into
libunicode
- updated unicode.py in src/etc to generate aforementioned tables
- generated new tables based on latest Unicode data
- added UnicodeChar and UnicodeStrSlice traits to prelude
- libunicode is now the collection point for the std::char module,
combining the libunicode functionality with the Char functionality
from libcore
- thus, moved doc comment for char from core::char to unicode::char
- libcollections remains the collection point for std::str
The Unicode-aware functions that previously lived in the Char and
StrSlice traits are no longer available to programs that only use
libcore. To regain use of these methods, include the libunicode crate
and use the UnicodeChar and/or UnicodeStrSlice traits:
extern crate unicode;
use unicode::UnicodeChar;
use unicode::UnicodeStrSlice;
use unicode::Words; // if you want to use the words() method
NOTE: this does *not* impact programs that use libstd, since UnicodeChar
and UnicodeStrSlice have been added to the prelude.

std: Recreate a `collections` module
As with the previous commit with `librand`, this commit shuffles around some
`collections` code. The new state of the world is similar to that of librand:
* The libcollections crate now only depends on libcore and liballoc.
* The standard library has a new module, `std::collections`. All functionality
of libcollections is reexported through this module.
I would like to stress that this change is purely cosmetic. There are very few
alterations to these primitives.
There are a number of notable points about the new organization:
* std::{str, slice, string, vec} all moved to libcollections. There is no reason
that these primitives shouldn't be necessarily usable in a freestanding
context that has allocation. These are all reexported in their usual places in
the standard library.
* The `hashmap`, and transitively the `lru_cache`, modules no longer reside in
`libcollections`, but rather in libstd. The reason for this is because the
`HashMap::new` contructor requires access to the OSRng for initially seeding
the hash map. Beyond this requirement, there is no reason that the hashmap
could not move to libcollections.
I do, however, have a plan to move the hash map to the collections module. The
`HashMap::new` function could be altered to require that the `H` hasher
parameter ascribe to the `Default` trait, allowing the entire `hashmap` module
to live in libcollections. The key idea would be that the default hasher would
be different in libstd. Something along the lines of:
// src/libstd/collections/mod.rs
pub type HashMap<K, V, H = RandomizedSipHasher> =
core_collections::HashMap<K, V, H>;
This is not possible today because you cannot invoke static methods through
type aliases. If we modified the compiler, however, to allow invocation of
static methods through type aliases, then this type definition would
essentially be switching the default hasher from `SipHasher` in libcollections
to a libstd-defined `RandomizedSipHasher` type. This type's `Default`
implementation would randomly seed the `SipHasher` instance, and otherwise
perform the same as `SipHasher`.
This future state doesn't seem incredibly far off, but until that time comes,
the hashmap module will live in libstd to not compromise on functionality.
* In preparation for the hashmap moving to libcollections, the `hash` module has
moved from libstd to libcollections. A previously snapshotted commit enables a
distinct `Writer` trait to live in the `hash` module which `Hash`
implementations are now parameterized over.
Due to using a custom trait, the `SipHasher` implementation has lost its
specialized methods for writing integers. These can be re-added
backwards-compatibly in the future via default methods if necessary, but the
FNV hashing should satisfy much of the need for speedier hashing.
A list of breaking changes:
* HashMap::{get, get_mut} no longer fails with the key formatted into the error
message with `{:?}`, instead, a generic message is printed. With backtraces,
it should still be not-too-hard to track down errors.
* The HashMap, HashSet, and LruCache types are now available through
std::collections instead of the collections crate.
* Manual implementations of hash should be parameterized over `hash::Writer`
instead of just `Writer`.

std: Recreate a `rand` module
This commit shuffles around some of the `rand` code, along with some
reorganization. The new state of the world is as follows:
* The librand crate now only depends on libcore. This interface is experimental.
* The standard library has a new module, `std::rand`. This interface will
eventually become stable.
Unfortunately, this entailed more of a breaking change than just shuffling some
names around. The following breaking changes were made to the rand library:
* Rng::gen_vec() was removed. This has been replaced with Rng::gen_iter() which
will return an infinite stream of random values. Previous behavior can be
regained with `rng.gen_iter().take(n).collect()`
* Rng::gen_ascii_str() was removed. This has been replaced with
Rng::gen_ascii_chars() which will return an infinite stream of random ascii
characters. Similarly to gen_iter(), previous behavior can be emulated with
`rng.gen_ascii_chars().take(n).collect()`
* {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all
relied on being able to use an OSRng for seeding, but this is no longer
available in librand (where these types are defined). To retain the same
functionality, these types now implement the `Rand` trait so they can be
generated with a random seed from another random number generator. This allows
the stdlib to use an OSRng to create seeded instances of these RNGs.
* Rand implementations for `Box<T>` and `@T` were removed. These seemed to be
pretty rare in the codebase, and it allows for librand to not depend on
liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not
supported. If this is undesirable, librand can depend on liballoc and regain
these implementations.
* The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`,
but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice
structure now has a lifetime associated with it.
* The `sample` method on `Rng` has been moved to a top-level function in the
`rand` module due to its dependence on `Vec`.

regained with `rng.gen_iter().take(n).collect()`
* Rng::gen_ascii_str() was removed. This has been replaced with
Rng::gen_ascii_chars() which will return an infinite stream of random ascii
characters. Similarly to gen_iter(), previous behavior can be emulated with
`rng.gen_ascii_chars().take(n).collect()`
* {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all
relied on being able to use an OSRng for seeding, but this is no longer
available in librand (where these types are defined). To retain the same
functionality, these types now implement the `Rand` trait so they can be
generated with a random seed from another random number generator. This allows
the stdlib to use an OSRng to create seeded instances of these RNGs.
* Rand implementations for `Box<T>` and `@T` were removed. These seemed to be
pretty rare in the codebase, and it allows for librand to not depend on
liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not
supported. If this is undesirable, librand can depend on liballoc and regain
these implementations.
* The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`,
but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice
structure now has a lifetime associated with it.
* The `sample` method on `Rng` has been moved to a top-level function in the
`rand` module due to its dependence on `Vec`.

std: Recreate a `rand` module
This commit shuffles around some of the `rand` code, along with some
reorganization. The new state of the world is as follows:
* The librand crate now only depends on libcore. This interface is experimental.
* The standard library has a new module, `std::rand`. This interface will
eventually become stable.
Unfortunately, this entailed more of a breaking change than just shuffling some
names around. The following breaking changes were made to the rand library:
* Rng::gen_vec() was removed. This has been replaced with Rng::gen_iter() which
will return an infinite stream of random values. Previous behavior can be
regained with `rng.gen_iter().take(n).collect()`
* Rng::gen_ascii_str() was removed. This has been replaced with
Rng::gen_ascii_chars() which will return an infinite stream of random ascii
characters. Similarly to gen_iter(), previous behavior can be emulated with
`rng.gen_ascii_chars().take(n).collect()`
* {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all
relied on being able to use an OSRng for seeding, but this is no longer
available in librand (where these types are defined). To retain the same
functionality, these types now implement the `Rand` trait so they can be
generated with a random seed from another random number generator. This allows
the stdlib to use an OSRng to create seeded instances of these RNGs.
* Rand implementations for `Box<T>` and `@T` were removed. These seemed to be
pretty rare in the codebase, and it allows for librand to not depend on
liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not
supported. If this is undesirable, librand can depend on liballoc and regain
these implementations.
* The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`,
but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice
structure now has a lifetime associated with it.
* The `sample` method on `Rng` has been moved to a top-level function in the
`rand` module due to its dependence on `Vec`.

std: Recreate a `collections` module
As with the previous commit with `librand`, this commit shuffles around some
`collections` code. The new state of the world is similar to that of librand:
* The libcollections crate now only depends on libcore and liballoc.
* The standard library has a new module, `std::collections`. All functionality
of libcollections is reexported through this module.
I would like to stress that this change is purely cosmetic. There are very few
alterations to these primitives.
There are a number of notable points about the new organization:
* std::{str, slice, string, vec} all moved to libcollections. There is no reason
that these primitives shouldn't be necessarily usable in a freestanding
context that has allocation. These are all reexported in their usual places in
the standard library.
* The `hashmap`, and transitively the `lru_cache`, modules no longer reside in
`libcollections`, but rather in libstd. The reason for this is because the
`HashMap::new` contructor requires access to the OSRng for initially seeding
the hash map. Beyond this requirement, there is no reason that the hashmap
could not move to libcollections.
I do, however, have a plan to move the hash map to the collections module. The
`HashMap::new` function could be altered to require that the `H` hasher
parameter ascribe to the `Default` trait, allowing the entire `hashmap` module
to live in libcollections. The key idea would be that the default hasher would
be different in libstd. Something along the lines of:
// src/libstd/collections/mod.rs
pub type HashMap<K, V, H = RandomizedSipHasher> =
core_collections::HashMap<K, V, H>;
This is not possible today because you cannot invoke static methods through
type aliases. If we modified the compiler, however, to allow invocation of
static methods through type aliases, then this type definition would
essentially be switching the default hasher from `SipHasher` in libcollections
to a libstd-defined `RandomizedSipHasher` type. This type's `Default`
implementation would randomly seed the `SipHasher` instance, and otherwise
perform the same as `SipHasher`.
This future state doesn't seem incredibly far off, but until that time comes,
the hashmap module will live in libstd to not compromise on functionality.
* In preparation for the hashmap moving to libcollections, the `hash` module has
moved from libstd to libcollections. A previously snapshotted commit enables a
distinct `Writer` trait to live in the `hash` module which `Hash`
implementations are now parameterized over.
Due to using a custom trait, the `SipHasher` implementation has lost its
specialized methods for writing integers. These can be re-added
backwards-compatibly in the future via default methods if necessary, but the
FNV hashing should satisfy much of the need for speedier hashing.
A list of breaking changes:
* HashMap::{get, get_mut} no longer fails with the key formatted into the error
message with `{:?}`, instead, a generic message is printed. With backtraces,
it should still be not-too-hard to track down errors.
* The HashMap, HashSet, and LruCache types are now available through
std::collections instead of the collections crate.
* Manual implementations of hash should be parameterized over `hash::Writer`
instead of just `Writer`.

Add libunicode; move unicode functions from core
- created new crate, libunicode, below libstd
- split Char trait into Char (libcore) and UnicodeChar (libunicode)
- Unicode-aware functions now live in libunicode
- is_alphabetic, is_XID_start, is_XID_continue, is_lowercase,
is_uppercase, is_whitespace, is_alphanumeric, is_control,
is_digit, to_uppercase, to_lowercase
- added width method in UnicodeChar trait
- determines printed width of character in columns, or None if it is
a non-NULL control character
- takes a boolean argument indicating whether the present context is
CJK or not (characters with 'A'mbiguous widths are double-wide in
CJK contexts, single-wide otherwise)
- split StrSlice into StrSlice (libcore) and UnicodeStrSlice
(libunicode)
- functionality formerly in StrSlice that relied upon Unicode
functionality from Char is now in UnicodeStrSlice
- words, is_whitespace, is_alphanumeric, trim, trim_left, trim_right
- also moved Words type alias into libunicode because words method is
in UnicodeStrSlice
- unified Unicode tables from libcollections, libcore, and libregex into
libunicode
- updated unicode.py in src/etc to generate aforementioned tables
- generated new tables based on latest Unicode data
- added UnicodeChar and UnicodeStrSlice traits to prelude
- libunicode is now the collection point for the std::char module,
combining the libunicode functionality with the Char functionality
from libcore
- thus, moved doc comment for char from core::char to unicode::char
- libcollections remains the collection point for std::str
The Unicode-aware functions that previously lived in the Char and
StrSlice traits are no longer available to programs that only use
libcore. To regain use of these methods, include the libunicode crate
and use the UnicodeChar and/or UnicodeStrSlice traits:
extern crate unicode;
use unicode::UnicodeChar;
use unicode::UnicodeStrSlice;
use unicode::Words; // if you want to use the words() method
NOTE: this does *not* impact programs that use libstd, since UnicodeChar
and UnicodeStrSlice have been added to the prelude.
closes #15224
