[−][src]Struct nonzero_signed::NonZeroI32
These became part of std::num in Rust 1.34, please use the std types instead of this crate.
An integer that is known not to equal zero.
This enables some memory layout optimization.
For example, Option<NonZeroI32>
is the same size as i32
:
use std::mem::size_of; use nonzero_signed::NonZeroI32; assert_eq!(size_of::<Option<NonZeroI32>>(), size_of::<i32>());
Methods
impl NonZeroI32

pub fn new(n: i32) -> Option<Self>
[src]

pub fn get(self) -> i32
[src]
Returns the value as a primitive type.
