Struct sync::Mutex

pub struct Mutex<T: ?Sized> {
    std: Mutex<T>,
}

A mutual exclusion primitive useful for protecting shared data.

Fields

std: Mutex<T>

Implementations

impl<T> Mutex<T>

pub const fn new(value: T) -> Mutex<T>

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

pub fn into_inner(self) -> T

Consumes this mutex, returning the underlying data.

impl<T: ?Sized> Mutex<T>

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

Acquires a mutex, blocking the current thread until it is able to do so.

This function will block the local thread until it is available to acquire the mutex. Upon returning, the thread is the only thread with the lock held. An RAII guard is returned to allow scoped unlock of the lock. When the guard goes out of scope, the mutex will be unlocked.

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

Attempts to acquire this lock.

If the lock could not be acquired at this time, then Err is returned. Otherwise, an RAII guard is returned. The lock will be unlocked when the guard is dropped.

This function does not block.

pub fn get_mut(&mut self) -> &mut T

Returns a mutable reference to the underlying data.

Since this call borrows the Mutex mutably, no actual locking needs to take place – the mutable borrow statically guarantees no locks exist.

Trait Implementations

impl<T: ?Sized + Debug> Debug for Mutex<T>

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default + ?Sized> Default for Mutex<T>

fn default() -> Mutex<T>

Returns the “default value” for a type.

impl<T> From<T> for Mutex<T>

fn from(value: T) -> Self

Converts to this type from the input type.
