1.34.0[−][src]Struct core::num::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) -> Self[src]
pub const fn new(n: isize) -> Option<Self>[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.
