Struct tokio::sync::Mutex

pub struct Mutex<T> { /* fields omitted */ }

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 lock, which guarantees that the data is only ever accessed when the mutex is locked.

Implementations

impl<T> Mutex<T>

pub fn new(t: T) -> Self

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

pub async fn lock(&self) -> MutexGuard<'_, T>

A future that resolves on acquiring the lock and returns the MutexGuard.

pub fn try_lock(&self) -> Result<MutexGuard<'_, T>, TryLockError>

Tries to acquire the lock
