Struct MutexGuard

pub struct MutexGuard<'a, T> {
    data: *mut T,
    lock: *const AtomicUsize,
    phantom: PhantomData<&'a Mutex<T>>,
}

An RAII implementation of a “scoped lock” of a mutex. When this structure is dropped (falls out of scope), the lock will be unlocked.

This struct must not implement Send.

Fields

data: *mut T

lock: *const AtomicUsize

phantom: PhantomData<&'a Mutex<T>>

Implementations

impl<'a, T> MutexGuard<'a, T>

pub fn map<O, F>(this: Self, f: F) -> MappedMutex<'a, O>

where F: FnOnce(&'a mut T) -> O + 'a,

Trait Implementations

impl<T> Deref for MutexGuard<'_, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for MutexGuard<'_, T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> Drop for MutexGuard<'_, T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: Sync> Sync for MutexGuard<'_, T>
