Make fields of mir::Terminator public
When trying to use the RA crate, I am unable to access the fields in `hir_def::mir::Terminator`.
I don't see any reason, why these should be private, especially as the fields of `hir_def::mir::Statement` are `pub`.
I am not sure if the fields in `hir_def::mir::SwitchTargets` should be made `pub` too, but at least they are read-accessible via some public methods..
Sorry if I missed something, this is my first PR.
Support GATs in bounds for associated types
Chalk has a dedicated IR for bounds on trait associated type: `rust_ir::InlineBound`. We have been failing to convert GATs inside those bounds from our IR to chalk IR. This PR provides an easy fix for it: properly take GATs into account during the conversion.
Map our diagnostics to rustc and clippy's ones
And control their severity by lint attributes `#[allow]`, `#[deny]` and ... .
It doesn't work with proc macros and I would like to fix that before merge but I don't know how to do it.
internal: Format let-else
As nightly finally got support for it I went ahead and formatted r-a with the latest nightly, then with the latest stable (in case other stuff changed)
Use anonymous lifetime where possible
Because anonymous lifetimes are *super* cool.
More seriously, I believe anonymous lifetimes, especially those in impl headers, reduce cognitive load to a certain extent because they usually signify that they are not relevant in the signature of the methods within (or that we can apply the usual lifetime elision rules even if they are relevant).
internal: support `#[rustc_coinductive]`
rust-lang/rust#100386 changed the trait solver so that `Sized` is treated as coinductive trait, just like auto traits. This is now controlled by the perma-unstable `#[rustc_coinductive]` attribute (rust-lang/rust#108033), which this PR adds support for.
In practice, I don't think this matters much if at all. Currently we don't give chalk enough information so chalk cannot precisely (dis)prove `Sized` bounds.
Added a test near positive extermes and two test near negative
extermes as well one for 0.
Added a test using the `as` cast and one with comparison with 0.
Reason: The last byte in Little Endian representation of negative
integers start at 128 (Ox80) till 255 (OxFF). The comparison before
the fix didn't check for 128 which made is_negative variable as false.
internal: remove spurious regex dependency
- replace tokio's env-filter with a smaller&simpler targets filter
- reshuffle logging infra a bit to make sure there's only a single place where we read environmental variables
- use anyhow::Result in rust-analyzer binary
