Struct RawMutex 

pub struct RawMutex { /* private fields */ }

A mutual exclusion primitive.

This lock disables interrupts on the current core while locked.

Implementations

impl RawMutex

pub const fn new() -> Self

Create a new lock.

pub unsafe fn acquire(&self) -> RestoreState

Acquires the lock.

Safety

• Each release call must be paired with an acquire call.
• The returned token must be passed to the corresponding release call.
• The caller must ensure to release the locks in the reverse order they were acquired.

pub unsafe fn release(&self, token: RestoreState)

Releases the lock.

Safety

• This function must only be called if the lock was acquired by the current thread.
• The caller must ensure to release the locks in the reverse order they were acquired.
• Each release call must be paired with an acquire call.

pub fn lock_non_reentrant<R>(&self, f: impl FnOnce() -> R) -> R

Runs the callback with this lock locked.

Note that this function is not reentrant, calling it reentrantly will panic.

pub fn lock<R>(&self, f: impl FnOnce() -> R) -> R

Runs the callback with this lock locked.
