Struct core::num::NonZeroU64 1.28.0[−][src]
#[repr(transparent)]pub struct NonZeroU64(_);
An integer that is known not to equal zero.
This enables some memory layout optimization.
For example, Option<NonZeroU32> is the same size as u32:
use std::mem::size_of; assert_eq!(size_of::<Option<std::num::NonZeroU32>>(), size_of::<u32>());Run
