Implementations

impl SlotH

const DESTINATION_BITS: usize = 8usize

const DESTINATION_OFFSET: usize = 24usize

const fn new() -> Self

Creates a new default initialized bitfield.

const fn from_bits(bits: u32) -> Self

Convert from bits.

const fn into_bits(self) -> u32

Convert into bits.

const fn destination(&self) -> u8

Interrupt destination.

The meaning of destination depends on the destination mode: For the logical destination mode, destination holds a bit mask made up of the cores that are candidates for receiving the interrupt. In the single-core case, this value is 1, in the multi-core case, the n low-order bits needs to be set (with n being the number of CPU cores). Setting the n low-order bits marks all available cores as candidates for receiving interrupts and thereby balancing the number of interrupts between the cores.

Bits: 24..32

const fn with_destination_checked(self, value: u8) -> Result<Self, ()>
