1.28.0[][src]Struct std::num::NonZeroU128

#[repr(transparent)]
pub struct NonZeroU128(_);

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, Option<NonZeroU128> is the same size as u128:

use std::mem::size_of;
assert_eq!(size_of::<Option<std::num::NonZeroU128>>(), size_of::<u128>());Run

Methods

impl NonZeroU128
[src]

Create a non-zero without checking the value.

Safety

The value must not be zero.

Create a non-zero if the given value is not zero.

Returns the value as a primitive type.
