Struct PreemptIrqSaveGuard 

pub struct PreemptIrqSaveGuard { /* private fields */ }

An RAII guard which disables preemption and local interrupts.

Entry disables preemption before interrupts. Drop restores interrupts before re-enabling preemption.

fn require_send<T: Send>() {}
require_send::<ax_sync::PreemptIrqSaveGuard>();

Trait Implementations

impl Default for PreemptIrqSaveGuard

fn default() -> Self

impl Drop for PreemptIrqSaveGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
