Struct spin::RwLockWriteGuard[−][src]

pub struct RwLockWriteGuard<'a, T: 'a + ?Sized> { /* fields omitted */ }
[−]

A guard to which the protected data can be written

When the guard falls out of scope it will release the lock.

Implementations

impl<'rwlock, T: ?Sized> RwLockWriteGuard<'rwlock, T>[src][−]

pub fn downgrade(self) -> RwLockReadGuard<'rwlock, T>[src][−]

Downgrades the writable lock guard to a readable, shared lock guard. Cannot fail and is guaranteed not to spin.

let mylock = spin::RwLock::new(0);

let mut writable = mylock.write();
*writable = 1;

let readable = writable.downgrade(); // This is guaranteed not to spin
assert_eq!(*readable, 1);
