//! Platform-dependent platform abstraction.
|
|
//!
|
|
//! The `std::sys` module is the abstracted interface through which
|
|
//! `std` talks to the underlying operating system. It has different
|
|
//! implementations for different operating system families, today
|
|
//! just Unix and Windows, and initial support for Redox.
|
|
//!
|
|
//! The centralization of platform-specific code in this module is
|
|
//! enforced by the "platform abstraction layer" tidy script in
|
|
//! `tools/tidy/src/pal.rs`.
|
|
//!
|
|
//! This module is closely related to the platform-independent system
|
|
//! integration code in `std::sys_common`. See that module's
|
|
//! documentation for details.
|
|
//!
|
|
//! In the future it would be desirable for the independent
|
|
//! implementations of this module to be extracted to their own crates
|
|
//! that `std` can link to, thus enabling their implementation
|
|
//! out-of-tree via crate replacement. Though due to the complex
|
|
//! inter-dependencies within `std` that will be a challenging goal to
|
|
//! achieve.
