Struct wasmtime_environ::__core::num::NonZeroIsize
1.34.0 · source · [−]#[repr(transparent)]pub struct NonZeroIsize(_);
Expand description
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>());
Implementations
sourceimpl NonZeroIsize
impl NonZeroIsize
const: 1.34.0 · sourcepub const unsafe fn new_unchecked(n: isize) -> NonZeroIsize
pub const unsafe fn new_unchecked(n: isize) -> NonZeroIsize
Creates a non-zero without checking whether the value is non-zero. This results in undefined behaviour if the value is zero.
Safety
The value must not be zero.
const: 1.47.0 · sourcepub const fn new(n: isize) -> Option<NonZeroIsize>
pub const fn new(n: isize) -> Option<NonZeroIsize>
Creates a non-zero if the given value is not zero.
sourceimpl NonZeroIsize
impl NonZeroIsize
1.53.0 (const: 1.53.0) · sourcepub const fn leading_zeros(self) -> u32
pub const fn leading_zeros(self) -> u32
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::NonZeroIsize::new(-1isize).unwrap();
assert_eq!(n.leading_zeros(), 0);
1.53.0 (const: 1.53.0) · sourcepub const fn trailing_zeros(self) -> u32
pub const fn trailing_zeros(self) -> u32
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::NonZeroIsize::new(0b0101000).unwrap();
assert_eq!(n.trailing_zeros(), 3);

sourcepub const fn checked_mul(self, other: NonZeroIsize) -> Option<NonZeroIsize>
🔬 This is a nightly-only experimental API. (nonzero_ops
)
pub const fn checked_mul(self, other: NonZeroIsize) -> Option<NonZeroIsize>
nonzero_ops
)Multiply two non-zero integers together.
Check for overflow and return None
on overflow.
As a consequence, the result cannot wrap to zero.
Examples
#![feature(nonzero_ops)]
let two = NonZeroIsize::new(2)?;
let four = NonZeroIsize::new(4)?;
let max = NonZeroIsize::new(isize::MAX)?;

sourcepub const unsafe fn unchecked_mul(self, other: NonZeroIsize) -> NonZeroIsize
🔬 This is a nightly-only experimental API. (nonzero_ops
)
pub const unsafe fn unchecked_mul(self, other: NonZeroIsize) -> NonZeroIsize
nonzero_ops
)Multiply two non-zero integers together,
assuming overflow cannot occur.
Overflow is unchecked, and it is undefined behaviour to overflow
even if the result would wrap to a non-zero value.
The behaviour is undefined as soon as
self * rhs > isize::MAX
, or self * rhs < isize::MIN
.
Examples
#![feature(nonzero_ops)]
let two = NonZeroIsize::new(2)?;
let four = NonZeroIsize::new(4)?;
assert_eq!(four, unsafe { two.unchecked_mul(two) });

nonzero_ops
)Raise non-zero value to an integer power.

Examples
#![feature(nonzero_ops)]
let three = NonZeroIsize::new(3)?;
let twenty_seven = NonZeroIsize::new(27)?;
let half_max = NonZeroIsize::new(isize::MAX / 2)?;

🔬 This is a nightly-only experimental API. (nonzero_ops
)
pub const fn saturating_pow(self, other: u32) -> NonZeroIsize
nonzero_ops
)Raise non-zero value to an integer power.

or isize::MAX
on overflow.
Examples

let three = NonZeroIsize::new(3)?;
let twenty_seven = NonZeroIsize::new(27)?;
let max = NonZeroIsize::new(isize::MAX)?;

)
pub const MIN: NonZeroIsize
nonzero_min_max
)The smallest value that can be represented by this non-zero
integer type,

Note: While most integer types are defined for every whole
number between MIN
