# Struct std::sync::MutexGuard

1.0.0 · source ·

    pub struct MutexGuard<'a, T: ?Sized + 'a> { /* private fields */ }

Expand description

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

The data protected by the mutex can be accessed through this guard via its `Deref` and `DerefMut` implementations.

This structure is created by the `lock` and `try_lock` methods on `Mutex`.
