std-semaphore
A counting, blocking semaphore extracted from rust 1.7.0.
Semaphores are a form of atomic counter where access is only granted if the counter is a positive value. Each acquisition will block the calling thread until the counter is positive, and each release will increment the counter and unblock any threads if necessary.
Usage
Add this to your Cargo.toml
:
[]
= "0.1"
and this to your crate root:
extern crate std_semaphore;
Examples
use Semaphore;
// Create a semaphore that represents 5 resources
let sem = new;
// Acquire one of the resources
sem.acquire;
// Acquire one of the resources for a limited period of time
// resources is released here
// Release our initially acquired resource
sem.release;
