Trait esp32_hal::xtensa_lx::interrupt::InterruptNumber

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

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.
