Trait IrqIf

pub trait IrqIf {
    // Required methods
    fn set_enable(irq: usize, enabled: bool);
    fn register(irq: usize, handler: IrqHandler) -> bool;
    fn unregister(irq: usize) -> Option<IrqHandler>;
    fn handle(irq: usize);
}

IRQ management interface.

Required Methods

fn set_enable(irq: usize, enabled: bool)

Enables or disables the given IRQ.

fn register(irq: usize, handler: IrqHandler) -> bool

Registers an IRQ handler for the given IRQ.

It also enables the IRQ if the registration succeeds. It returns false if the registration failed.

fn unregister(irq: usize) -> Option<IrqHandler>

Unregisters the IRQ handler for the given IRQ.

It also disables the IRQ if the unregistration succeeds. It returns the existing handler if it is registered, None otherwise.

fn handle(irq: usize)

Handles the IRQ.

It is called by the common interrupt handler. It should look up in the IRQ handler table and calls the corresponding handler. If necessary, it also acknowledges the interrupt controller after handling.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
