1.34.0[][src]Struct std::num::NonZeroIsize

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

An integer that is known not to equal zero.

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

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

Methods

impl NonZeroIsize[src]

pub const unsafe fn new_unchecked(n: isize) -> NonZeroIsize[src]

Creates a non-zero without checking the value.

Safety

The value must not be zero.

pub fn new(n: isize) -> Option<NonZeroIsize>[src]

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

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

Returns the value as a primitive type.
