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. #![allow(missing_debug_implementations)] pub use self::imp::*; #[cfg(unix)] #[path = "unix/mod.rs"] mod imp; #[cfg(windows)] #[path = "windows/mod.rs"] mod imp; #[cfg(target_os = "redox")] #[path = "redox/mod.rs"] mod imp; // Import essential modules from both platforms when documenting. #[cfg(all(dox, not(unix)))] use os::linux as platform; #[cfg(all(dox, not(any(unix, target_os = "redox"))))] #[path = "unix/ext/mod.rs"] pub mod unix_ext; #[cfg(all(dox, any(unix, target_os = "redox")))] pub use self::ext as unix_ext; #[cfg(all(dox, not(windows)))] #[macro_use] #[path = "windows/compat.rs"] mod compat; #[cfg(all(dox, not(windows)))] #[path = "windows/c.rs"] mod c; #[cfg(all(dox, not(windows)))] #[path = "windows/ext/mod.rs"] pub mod windows_ext; #[cfg(all(dox, windows))] pub use self::ext as windows_ext;
