//!Semaphore primitive for Rust
//!
//!## Platform implementation
//!
//!#### Windows
//!
//!Uses winapi `CreateSemaphoreW`.
//!
//!#### POSIX
//!
//!All POSIX-compliant systems uses `sem_init`
//!But it must be noted that awaiting can be interrupted by the signal, although implementation
//!tries its best to handle these cases
//!
//!POSIX implementation relies on [libc](https://github.com/rust-lang/libc)
//!
//!This includes all `unix` targets and `fuchsia`
//!
//!### Mac
//!
//!Uses `mach` API.
