Struct Lock

pub struct Lock<T> { /* private fields */ }

An asynchronous mutual exclusion primitive useful for protecting shared data

Each mutex has a type parameter (T) which represents the data that it is protecting. The data can only be accessed through the RAII guards returned from poll_lock, which guarantees that the data is only ever accessed when the mutex is locked.

Implementations

impl<T> Lock<T>

pub fn new(t: T) -> Self

Creates a new lock in an unlocked state ready for use.

pub fn poll_lock(&mut self) -> Async<LockGuard<T>>

Try to acquire the lock.

If the lock is already held, the current task is notified when it is released.

Trait Implementations

impl<T> Clone for Lock<T>

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)

impl<T> Default for Lock<T>

where T: Default,

fn default() -> Self

impl<T> From<T> for Lock<T>

fn from(s: T) -> Self
