std::u8
Primitive Type u8
The 8-bit unsigned integer type.
However, please note that examples are shared between primitive integer types. So it's normal if you see usage of types like u64
in there.
Methods

Returns the smallest value that can be represented by this integer type.
Examples
assert_eq!(u8::min_value(), 0);

fn wrapping_div(self, rhs: u8) -> u8
1.2.0
Wrapping (modular) division. Computes self / other
. Wrapped division on unsigned types is just normal division. There's no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations.
Examples
Basic usage:
assert_eq!(100u8.wrapping_div(10), 10);
fn wrapping_rem(self, rhs: u8) -> u8
1.2.0
Wrapping (modular) remainder. Computes self % other
. Wrapped remainder calculation on unsigned types is just the regular remainder calculation. There's no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations.
Examples
Basic usage:
assert_eq!(100u8.wrapping_rem(10), 0);
fn wrapping_neg(self) -> u8
1.2.0
Wrapping (modular) negation. Computes -self
, wrapping around at the boundary of the type.
Since unsigned types do not have negative equivalents all applications of this function will wrap (except for -0
). For values smaller than the corresponding signed type's maximum the result is the same as casting the corresponding signed value. Any larger values are equivalent to MAX + 1 - (val - MAX - 1)
where MAX
is the corresponding signed type's maximum.
Examples
Basic usage:
assert_eq!(100u8.wrapping_neg(), 156); assert_eq!(0u8.wrapping_neg(), 0); assert_eq!(180u8.wrapping_neg(), 76); assert_eq!(180u8.wrapping_neg(), (127 + 1) - (180u8 - (127 + 1)));
fn wrapping_shl(self, rhs: u32) -> u8
1.2.0
Panic-free bitwise shift-left; yields self << mask(rhs)
, where mask
removes any high-order bits of rhs
that would cause the shift to exceed the bitwidth of the type.
Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_left
function, which may be what you want instead.
Examples
Basic usage:
assert_eq!(1u8.wrapping_shl(7), 128); assert_eq!(1u8.wrapping_shl(8), 1);
fn wrapping_shr(self, rhs: u32) -> u8
1.2.0
Panic-free bitwise shift-right; yields self >> mask(rhs)
, where mask
removes any high-order bits of rhs
that would cause the shift to exceed the bitwidth of the type.
Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_right
function, which may be what you want instead.
Examples
Basic usage:
assert_eq!(128u8.wrapping_shr(7), 1); assert_eq!(128u8.wrapping_shr(8), 128);
fn overflowing_add(self, rhs: u8) -> (u8, bool)
1.7.0
Calculates self
+ rhs
Returns a tuple of the addition along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.
Examples
Basic usage
use std::u32; assert_eq!(5u32.overflowing_add(2), (7, false)); assert_eq!(u32::MAX.overflowing_add(1), (0, true));
fn overflowing_sub(self, rhs: u8) -> (u8, bool)
1.7.0
Calculates self
- rhs
Returns a tuple of the subtraction along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.
Examples

use std::u32; assert_eq!(5u32.overflowing_sub(2), (3, false)); assert_eq!(0u32.overflowing_sub(1), (u32::MAX, true));
fn overflowing_mul(self, rhs: u8) -> (u8, bool)
1.7.0
Calculates the multiplication of self
and rhs
.
Returns a tuple of the multiplication along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.
Examples
Basic usage
assert_eq!(5u32.overflowing_mul(2), (10, false)); assert_eq!(1_000_000_000u32.overflowing_mul(10), (1410065408, true));
fn overflowing_div(self, rhs: u8) -> (u8, bool)
1.7.0
Calculates the divisor when self
is divided by rhs
.
Returns a tuple of the divisor along with a boolean indicating whether an arithmetic overflow would occur. Note that for unsigned integers overflow never occurs, so the second value is always false
.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage
assert_eq!(5u32.overflowing_div(2), (2, false));
fn overflowing_rem(self, rhs: u8) -> (u8, bool)
1.7.0
Calculates the remainder when self
is divided by rhs
.
Returns a tuple of the remainder after dividing along with a boolean indicating whether an arithmetic overflow would occur. Note that for unsigned integers overflow never occurs, so the second value is always false
.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage
assert_eq!(5u32.overflowing_rem(2), (1, false));
fn overflowing_neg(self) -> (u8, bool)
1.7.0
Negates self in an overflowing fashion.
Returns !self + 1
using wrapping operations to return the value that represents the negation of this unsigned value. Note that for positive unsigned values overflow always occurs, but negating 0 does not overflow.
Examples
Basic usage
assert_eq!(0u32.overflowing_neg(), (0, false)); assert_eq!(2u32.overflowing_neg(), (-2i32 as u32, true));
fn overflowing_shl(self, rhs: u32) -> (u8, bool)
1.7.0
Shifts self left by rhs
bits.
Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.
Examples
Basic usage
assert_eq!(0x10u32.overflowing_shl(4), (0x100, false)); assert_eq!(0x10u32.overflowing_shl(36), (0x100, true));
fn overflowing_shr(self, rhs: u32) -> (u8, bool)
1.7.0
Shifts self right by rhs
bits.
Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.
Examples
Basic usage
assert_eq!(0x10u32.overflowing_shr(4), (0x1, false)); assert_eq!(0x10u32.overflowing_shr(36), (0x1, true));
fn pow(self, exp: u32) -> u8
Raises self to the power of exp
, using exponentiation by squaring.

Returns true
if and only if self == 2^k
for some k
.

assert!(16u8.is_power_of_two()); assert!(!10u8.is_power_of_two());
fn next_power_of_two(self) -> u8
Returns the smallest power of two greater than or equal to self
. Unspecified behavior on overflow.
Examples
Basic usage:
assert_eq!(2u8.next_power_of_two(), 2); assert_eq!(3u8.next_power_of_two(), 4);
fn checked_next_power_of_two(self) -> Option<u8>
Returns the smallest power of two greater than or equal to n
. If the next power of two is greater than the type's maximum value, None
is returned, otherwise the power of two is wrapped in Some
.
Examples
Basic usage:
assert_eq!(2u8.checked_next_power_of_two(), Some(2)); assert_eq!(3u8.checked_next_power_of_two(), Some(4)); assert_eq!(200u8.checked_next_power_of_two(), None);
