Platform-dependent platform abstraction.
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
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
std can link to, thus enabling their implementation
out-of-tree via crate replacement. Though due to the complex
std that will be a challenging goal to
