Struct rustpython_common::lock::RawThreadMutex

pub struct RawThreadMutex<R: RawMutex, G: GetThreadId> { /* private fields */ }

A mutex type that knows when it would deadlock

Implementations

impl<R: RawMutex, G: GetThreadId> RawThreadMutex<R, G>

pub const INIT: Self = _

pub fn lock(&self) -> bool

Blocks for the mutex to be available, and returns true if the mutex isn’t already locked on the current thread.

pub fn try_lock(&self) -> Option<bool>

Returns Some(true) if able to successfully lock without blocking, Some(false) otherwise, and None when the mutex is already locked on the current thread.

pub unsafe fn unlock(&self)

Unlocks this mutex. The inner mutex may not be unlocked if this mutex was acquired previously in the current thread.

Safety

This method may only be called if the mutex is held by the current thread.
