This is intended to maintain existing standards of code organization in hopes that the standard library will continue to be refactored to isolate platform-specific bits, making porting easier; where "standard library" roughly means "all the dependencies of the std and test crates". This generally means placing restrictions on where `cfg(unix)`, `cfg(windows)`, `cfg(target_os)` and `cfg(target_env)` may appear, the basic objective being to isolate platform-specific code to the platform-specific `std::sys` modules, and to the allocation, unwinding, and libc crates. Following are the basic rules, though there are currently exceptions: - core may not have platform-specific code - liballoc_system may have platform-specific code - liballoc_jemalloc may have platform-specific code - libpanic_abort may have platform-specific code - libpanic_unwind may have platform-specific code - other crates in the std facade may not - std may have platform-specific code in the following places - sys/unix/ - sys/windows/ - os/ There are plenty of exceptions today though, noted in the whitelist.
