[][src]Struct nonzero_signed::NonZeroI8

#[repr(transparent)]
pub struct NonZeroI8(_);
Deprecated since 1.0.3:

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 NonZeroI8[src]

pub unsafe fn new_unchecked(n: i8) -> Self[src]

Create a non-zero without checking the value.

Safety

The value must not be zero.

pub fn new(n: i8) -> Option<Self>[src]

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

pub fn get(self) -> i8[src]

Returns the value as a primitive type.
