Struct ockam_core::lib::num::NonZeroU16 1.28.0[−][src]
#[repr(transparent)]pub struct NonZeroU16(_);
An integer that is known not to equal zero.
This enables some memory layout optimization.
For example, Option<NonZeroU16>
is the same size as u16
:
use std::mem::size_of; assert_eq!(size_of::<Option<core::num::NonZeroU16>>(), size_of::<u16>());
Implementations
impl NonZeroU16
[src]
impl NonZeroU16
[src]pub const unsafe fn new_unchecked(n: u16) -> NonZeroU16
1.28.0 (const: 1.28.0)[src]
pub const fn new(n: u16) -> Option<NonZeroU16>
1.28.0 (const: 1.47.0)[src]
Creates a non-zero if the given value is not zero.
pub const fn get(self) -> u16
1.28.0 (const: 1.34.0)[src]
Returns the value as a primitive type.
impl NonZeroU16
[src]
impl NonZeroU16
[src]pub const fn leading_zeros(self) -> u32
1.53.0 (const: 1.53.0)[src]
Returns the number of leading zeros in the binary representation of self
.
On many architectures, this function can perform better than leading_zeros()
on the underlying integer type, as special handling of zero can be avoided.
Examples
Basic usage:
let n = std::num::NonZeroU16::new(u16::MAX).unwrap(); assert_eq!(n.leading_zeros(), 0);
pub const fn trailing_zeros(self) -> u32
1.53.0 (const: 1.53.0)[src]
Returns the number of trailing zeros in the binary representation
of self
.
On many architectures, this function can perform better than trailing_zeros()
on the underlying integer type, as special handling of zero can be avoided.
Examples
Basic usage:
let n = std::num::NonZeroU16::new(0b0101000).unwrap(); assert_eq!(n.trailing_zeros(), 3);
impl NonZeroU16
[src]
impl NonZeroU16
[src]pub const fn is_power_of_two(self) -> bool
[src]
nonzero_is_power_of_two
)Returns true
if and only if self == (1 << k)
for some k
.
On many architectures, this function can perform better than is_power_of_two()
on the underlying integer type, as special handling of zero can be avoided.
Examples
Basic usage:
#![feature(nonzero_is_power_of_two)] let eight = std::num::NonZeroU16::new(8).unwrap(); assert!(eight.is_power_of_two()); let ten = std::num::NonZeroU16::new(10).unwrap(); assert!(!ten.is_power_of_two());
