Trait Mutex 

pub trait Mutex: Sized {
    // Required methods
    fn new() -> Option<Self>;
    fn lock(&self) -> MutexGuard<'_, Self>;
    fn try_lock(&self) -> Option<MutexGuard<'_, Self>>;
    fn unlock(&self, token: GuardToken);
}

Describes Mutex interface

Required Methods

fn new() -> Option<Self>

Creates new instance

Returns if Semaphore is successfully created.

fn lock(&self) -> MutexGuard<'_, Self>

Acquires lock, returning guard that unlocks self on drop.

If lock is already acquired, it blocks until mutex is unlocked

fn try_lock(&self) -> Option<MutexGuard<'_, Self>>

Attempts to acquire lock, returning guard that unlocks self on drop.

If lock is already acquired, it returns None

fn unlock(&self, token: GuardToken)

Tells how to perform unlock.

Method implementation should be safe, but is allowed to mis-behave when invoked without prior lock

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
