Struct std::num::NonZeroU8 [] [src]

pub struct NonZeroU8(_);
🔬 This is a nightly-only experimental API. (nonzero #49137)

An integer that is known not to equal zero.

This may enable some memory layout optimization such as:

use std::mem::size_of;
assert_eq!(size_of::<Option<std::num::NonZeroU32>>(), size_of::<u32>());Run
