1.28.0[][src]Struct std::num::NonZeroU16

#[repr(transparent)]
pub struct NonZeroU16(_);

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, Option<NonZeroU16> is the same size as u16:

use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroU16>>(), size_of::<u16>());Run

Methods

impl NonZeroU16[src]

pub const unsafe fn new_unchecked(n: u16) -> NonZeroU16[src]

Creates a non-zero without checking the value.

Safety

The value must not be zero.

pub fn new(n: u16) -> Option<NonZeroU16>[src]

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

pub const fn get(self) -> u16[src]

Returns the value as a primitive type.
