Function u64_into_u8 

pub const fn u64_into_u8<const N: u64>() -> u8

Performs a build-time safe conversion of a u64 constant value into a u8.

This checks at compile-time that the conversion is lossless, and triggers a build error if it isn’t.

Examples

use kernel::num::casts;

// Succeeds because the value of the source fits into the destination's type.
assert_eq!(casts::u64_into_u8::<1u64>(), 1u8);
