Struct miri::concurrency::sync::Mutex

struct Mutex {
    owner: Option<ThreadId>,
    lock_count: usize,
    queue: VecDeque<ThreadId>,
    data_race: VClock,
}

The mutex state.

Fields

owner: Option<ThreadId>

The thread that currently owns the lock.

lock_count: usize

How many times the mutex was locked by the owner.

queue: VecDeque<ThreadId>

The queue of threads waiting for this mutex.

data_race: VClock

Data race handle, this tracks the happens-before relationship between each mutex access. It is released to during unlock and acquired from during locking, and therefore stores the clock of the last thread to release this mutex.

Trait Implementations

impl Debug for Mutex

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

Formats the value using the given formatter.

impl Default for Mutex

fn default() -> Mutex

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
