1.28.0[][src]Struct sgx_tstd::num::NonZeroU128

#[repr(transparent)]pub struct NonZeroU128(_);

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, Option<NonZeroU128> is the same size as u128:

use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroU128>>(), size_of::<u128>());


impl NonZeroU128[src]

pub unsafe fn new_unchecked(n: u128) -> NonZeroU128[src]

Creates a non-zero without checking the value.


The value must not be zero.

pub fn new(n: u128) -> Option<NonZeroU128>[src]

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

pub fn get(self) -> u128[src]

Returns the value as a primitive type.
