Struct irq_safety::HeldInterrupts

source · 
pub struct HeldInterrupts(/* private fields */);
Expand description

A guard type for withholding regular interrupts on the current CPU.

When dropped, interrupts are returned to their prior state rather than just blindly re-enabled. For example, if interrupts were enabled when hold_interrupts() was invoked, interrupts will be re-enabled when this type is dropped.
