Struct IrqSaveGuard 

pub struct IrqSaveGuard { /* private fields */ }

An RAII guard which saves and disables local interrupts while it is alive.

Implementations

impl IrqSaveGuard

pub fn new() -> Self

pub fn disable_preempt_for_irq_return(&mut self) -> IrqReturnPreemptGuard<'_>

Disables preemption for work completed by a hard-IRQ return epilogue.

The mutable borrow prevents raw local-IRQ restoration before the dedicated preemption exit has completed.

Trait Implementations

impl Default for IrqSaveGuard

fn default() -> Self

Returns the “default value” for a type.

impl Drop for IrqSaveGuard

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.
