AutoPreemptDisabler

Struct AutoPreemptDisabler 

Source
pub struct AutoPreemptDisabler { /* private fields */ }
Expand description

RAII guard that disables preemption for its scope.

This guard is !Send and !Sync because preemption state is CPU- and thread-local.

Implementations§

Source§

impl AutoPreemptDisabler

Source

pub fn new() -> Self

Creates a new guard and immediately disables preemption.

Source

pub fn new_deferred() -> Self

Creates a new guard without immediately disabling preemption.

Source

pub fn disable(&mut self)

Disables preemption if not already disabled by this guard instance.

Source

pub fn enable(&mut self)

Re-enables preemption if previously disabled by this guard instance.

Source

pub fn is_disabled(&self) -> bool

Returns whether preemption is currently disabled by this guard instance.
