Struct PreemptGuard 

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

Preemption guard for disabling preemption without disabling interrupts.

This allows critical sections that need to prevent preemption but still allow interrupt handling (e.g., for device drivers).

Implementations§

Source§

impl PreemptGuard

Source

pub fn enter() -> Self

Enter a preemption-disabled critical section.

§Returns

A guard that will re-enable preemption when dropped.

Source

pub fn is_disabled() -> bool

Check if preemption is currently disabled.
