Trait InterruptNumber

pub unsafe trait InterruptNumber: Copy {
    // Required method
    fn number(self) -> u16;
}

Trait for enums of external interrupt numbers.

This trait should be implemented by a peripheral access crate (PAC) on its enum of available external interrupts for a specific device. Each variant must convert to a u16 of its interrupt number, which is its exception number - 16.

Safety

This trait must only be implemented on enums of device interrupts. Each enum variant must represent a distinct value (no duplicates are permitted), and must always return the same value (do not change at runtime).

These requirements ensure safe nesting of critical sections.

Required Methods

fn number(self) -> u16

Return the interrupt number associated with this variant.

See trait documentation for safety requirements.

Object Safety

This trait is not object safe.

Implementors

impl<T: Nr + Copy> InterruptNumber for T

Implement InterruptNumber for the old bare_metal::Nr trait. This implementation is for backwards compatibility only and will be removed in cortex-m 0.8.
