It seems a little strange to pull the IoSlice types from somewhere with “unsupported” in the name, as these types are actually used and supported on this target.

Yea, good point. I can't think of a good place to put this module, since there isn't a location for "basic implementation that is not Unix". Would it make sense to add a sys::basic module that contained code like this? The only other "functional" code in the unsupported tree is:

  • cmath.rs (basic definitions from compiler-builtins)
  • common.rs strlen (very simple pure-rust C-strlen implementation)
pub mod memchr;
pub mod mutex;
pub mod net;
pub mod os;
pub mod path;
#[path = "../unsupported/pipe.rs"]
pub mod pipe;
#[path = "../unsupported/process.rs"]
pub mod process;
pub mod rwlock;
pub mod stack_overflow;
