Trait riscv_pac::InterruptNumber

pub unsafe trait InterruptNumber: Copy {
    const MAX_INTERRUPT_NUMBER: u16;

    // Required methods
    fn number(self) -> u16;
    fn from_number(value: u16) -> Result<Self, u16>;
}

Trait for enums of target-specific 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.

Safety

• This trait must only be implemented on a PAC of a RISC-V target.
• This trait must only be implemented on enums of external interrupts.
• Each enum variant must represent a distinct value (no duplicates are permitted),
• Each enum variant must always return the same value (do not change at runtime).
• All the interrupt numbers must be less than or equal to MAX_INTERRUPT_NUMBER.
• MAX_INTERRUPT_NUMBER must coincide with the highest allowed interrupt number.

Required Associated Constants

const MAX_INTERRUPT_NUMBER: u16

Highest number assigned to an interrupt source.

Required Methods

fn number(self) -> u16

Converts an interrupt source to its corresponding number.

fn from_number(value: u16) -> Result<Self, u16>

Tries to convert a number to a valid interrupt source. If the conversion fails, it returns an error with the number back.

Object Safety

This trait is not object safe.
