IrqSaveGuard

ax_task::sync::api

Struct IrqSaveGuard 

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

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

The saved IRQ state belongs to the acquiring CPU, so the guard cannot be transferred to another execution context:

ⓘ
fn require_send<T: Send>() {}
require_send::<ax_task::sync::IrqSaveGuard>();
