Trait Mutex

pub trait Mutex {
    type Data;

    // Required method
    fn lock<'a, R>(&'a self, f: impl FnOnce(&'a mut Self::Data) -> R) -> R;
}

Any object implementing this trait guarantees exclusive access to the data wrapped within the Mutex for the duration of the provided closure.

Required Associated Types

type Data

The type of the data that is wrapped by this mutex.

Required Methods

fn lock<'a, R>(&'a self, f: impl FnOnce(&'a mut Self::Data) -> R) -> R

Locks the mutex and grants the closure temporary mutable access to the wrapped data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
