# Primitive Type u81.0.0 [−]

The 8-bit unsigned integer type.

See also the `std::u8` module.

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

### `impl u8`[src]

#### `pub const fn min_value() -> u8`[src]

Returns the smallest value that can be represented by this integer type.

# Examples

Basic usage:

`assert_eq!(u8::min_value(), 0);Run`

#### `pub const fn max_value() -> u8`[src]

Returns the largest value that can be represented by this integer type.

# Examples

Basic usage:

`assert_eq!(u8::max_value(), 255);Run`

#### `pub fn from_str_radix(src: &str, radix: u32) -> Result<u8, ParseIntError>`[src]

Converts a string slice in a given base to an integer.

The string is expected to be an optional `+` sign followed by digits. Leading and trailing whitespace represent an error. Digits are a subset of these characters, depending on `radix`:

• `0-9`
• `a-z`
• `A-Z`

# Panics

This function panics if `radix` is not in the range from 2 to 36.

# Examples

Basic usage:

`assert_eq!(u32::from_str_radix("A", 16), Ok(10));Run`

#### `pub fn count_ones(self) -> u32`[src]

Returns the number of ones in the binary representation of `self`.

# Examples

Basic usage:

```let n = 0b01001100u8;

assert_eq!(n.count_ones(), 3);Run```

#### `pub fn count_zeros(self) -> u32`[src]

Returns the number of zeros in the binary representation of `self`.

#### `pub fn wrapping_div(self, rhs: u8) -> u8`1.2.0[src]

Wrapping (modular) division. Computes `self / rhs`. 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

#### `pub fn wrapping_rem(self, rhs: u8) -> u8`1.2.0[src]

Wrapping (modular) remainder. Computes `self % rhs`. 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);Run`

#### `pub fn wrapping_neg(self) -> u8`1.2.0[src]

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)));Run```

#### `pub fn wrapping_shl(self, rhs: u32) -> u8`1.2.0[src]

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);Run```

#### `pub fn wrapping_shr(self, rhs: u32) -> u8`1.2.0[src]

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);Run```

#### `pub fn overflowing_add(self, rhs: u8) -> (u8, bool)`1.7.0[src]

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));Run```

#### `pub fn overflowing_sub(self, rhs: u8) -> (u8, bool)`1.7.0[src]

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

Basic usage

assert_eq!(0u32.overflowing_sub(1), (u32::MAX, true));Run```

#### `pub fn overflowing_mul(self, rhs: u8) -> (u8, bool)`1.7.0[src]

assert_eq!(1_000_000_000u32.overflowing_mul(10), (1410065408, true));Run```

#### `pub fn overflowing_div(self, rhs: u8) -> (u8, bool)`1.7.0[src]

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));Run`

#### `pub fn overflowing_rem(self, rhs: u8) -> (u8, bool)`1.7.0[src]

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));Run`

#### `pub fn overflowing_neg(self) -> (u8, bool)`1.7.0[src]

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));Run```

#### `pub fn overflowing_shl(self, rhs: u32) -> (u8, bool)`1.7.0[src]

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));Run```

#### `pub fn overflowing_shr(self, rhs: u32) -> (u8, bool)`1.7.0[src]

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));Run```

#### `pub fn pow(self, exp: u32) -> u8`[src]

# Examples

Basic usage:

`assert_eq!(2u32.pow(4), 16);Run`

#### `pub fn is_power_of_two(self) -> bool`[src]

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

# Examples

Basic usage:

```assert!(16u8.is_power_of_two());
assert!(!10u8.is_power_of_two());Run```

#### `pub fn next_power_of_two(self) -> u8`[src]

Returns the smallest power of two greater than or equal to `self`.

When return value overflows (i.e. `self > (1 << (N-1))` for type `uN`), it panics in debug mode and return value is wrapped to 0 in release mode (the only situation in which method can return 0).

# Examples

Basic usage:

```assert_eq!(2u8.next_power_of_two(), 2);
assert_eq!(3u8.next_power_of_two(), 4);Run```

#### `pub fn checked_next_power_of_two(self) -> Option<u8>`[src]

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`.

assert_eq!(3u8.checked_next_power_of_two(), Some(4));
assert_eq!(200u8.checked_next_power_of_two(), None);Run```

assert!(!non_ascii.is_ascii());Run```

#### `pub fn to_ascii_uppercase(&self) -> u8`1.23.0[src]

assert!(lowercase_a.eq_ignore_ascii_case(&uppercase_a));Run```

#### `pub fn make_ascii_uppercase(&mut self)`1.23.0[src]

• U+0041 'A' ... U+0046 'F', or
• U+0061 'a' ... U+0066 'f'.

# Examples

```#![feature(ascii_ctype)]

let uppercase_a = b'A';
let uppercase_g = b'G';
let a = b'a';
let g = b'g';
let zero = b'0';
let percent = b'%';
let space = b' ';
let lf = b'\n';
let esc = 0x1b_u8;

assert!(uppercase_a.is_ascii_hexdigit());
assert!(!uppercase_g.is_ascii_hexdigit());
assert!(a.is_ascii_hexdigit());
assert!(!g.is_ascii_hexdigit());
assert!(zero.is_ascii_hexdigit());
assert!(!percent.is_ascii_hexdigit());

• U+005B ... U+0060 `[ \ ] ^ _ ``, or
• U+007B ... U+007E `{ | } ~`

# Examples

```#![feature(ascii_ctype)]

let uppercase_a = b'A';
let uppercase_g = b'G';
let a = b'a';
let g = b'g';
let zero = b'0';
let percent = b'%';

# Examples

```#![feature(ascii_ctype)]

let uppercase_g = b'G';
let a = b'a';
let g = b'g';
let zero = b'0';

#### `pub fn is_ascii_whitespace(&self) -> bool`1.24.0[src]

Checks if the value is an ASCII whitespace character: U+0020 SPACE, U+0009 HORIZONTAL TAB, U+000A LINE FEED, U+000C FORM FEED, or U+000D CARRIAGE RETURN.

Rust uses the WhatWG Infra Standard's definition of ASCII whitespace. There are several other definitions in wide use. For instance, the POSIX locale includes U+000B VERTICAL TAB as well as all the above characters, but—from the very same specification—the default rule for "field splitting" in the Bourne shell considers only SPACE, HORIZONTAL TAB, and LINE FEED as whitespace.

If you are writing a program that will process an existing file format, check what that format's definition of whitespace is before using this function.

# Examples

```#![feature(ascii_ctype)]

let uppercase_a = b'A';
let uppercase_g = b'G';
let a = b'a';
let g = b'g';
let zero = b'0';
let percent = b'%';
let space = b' ';
let lf = b'\n';
let esc = 0x1b_u8;

assert!(!uppercase_a.is_ascii_whitespace());
assert!(!uppercase_g.is_ascii_whitespace());
assert!(!a.is_ascii_whitespace());
assert!(!g.is_ascii_whitespace());
assert!(!zero.is_ascii_whitespace());
assert!(!percent.is_ascii_whitespace());
assert!(space.is_ascii_whitespace());
assert!(lf.is_ascii_whitespace());
assert!(!esc.is_ascii_whitespace());Run```

#### `pub fn is_ascii_control(&self) -> bool`1.24.0[src]

Checks if the value is an ASCII control character: U+0000 NUL ... U+001F UNIT SEPARATOR, or U+007F DELETE. Note that most ASCII whitespace characters are control characters, but SPACE is not.

# Examples

```#![feature(ascii_ctype)]

let uppercase_a = b'A';
let uppercase_g = b'G';
let a = b'a';
let g = b'g';
let zero = b'0';
let percent = b'%';
let space = b' ';
let lf = b'\n';
let esc = 0x1b_u8;

assert!(!uppercase_a.is_ascii_control());
assert!(!uppercase_g.is_ascii_control());
