[−] Expand description

Structure representing a statically allocated RwLock.

This structure is intended to be used inside of a static and will provide automatic global access as well as lazy initialization. The internal resources of this RwLock, however, must be manually deallocated.

Examples

#![feature(static_rwlock)]

use std::sync::{StaticRwLock, RW_LOCK_INIT};

static LOCK: StaticRwLock = RW_LOCK_INIT;

{
    let _g = LOCK.read().unwrap();
    // ... shared read access
}
{
    let _g = LOCK.write().unwrap();
    // ... exclusive write access
}
unsafe { LOCK.destroy() } // free all resources
