| //! 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. |
