# Primitive Type u81.0.0 [−]

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

`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:

`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`

`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.

`pub fn wrapping_rem(self, rhs: u8) -> u8`

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

whether an arithmetic overflow would occur. Note that for unsigned
integers overflow never occurs, so the second value is always
`false`

.

This function will panic if `rhs`

is 0.

# Examples

Basic usage

assert_eq!(5u32.overflowing_div(2), (2, false));Run

1.7.0[src]

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.

for type
`uN`

release mode (the only situation in which method can return 0).

`pub fn is_ascii_punctuation(&self) -> bool`

1.24.0[src]

- U+0021 ... U+002F
`! " # $ % & ' ( ) * + , - . /`

, or - U+003A ... U+0040
`: ; < = > ? @`

, or - 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'%'; let space = b' '; let lf = b'\n'; let esc = 0x1b_u8; assert!(!uppercase_a.is_ascii_punctuation()); assert!(!uppercase_g.is_ascii_punctuation()); assert!(!a.is_ascii_punctuation()); assert!(!g.is_ascii_punctuation()); assert!(!zero.is_ascii_punctuation()); assert!(percent.is_ascii_punctuation()); assert!(!space.is_ascii_punctuation()); assert!(!lf.is_ascii_punctuation()); assert!(!esc.is_ascii_punctuation());Run

`pub fn is_ascii_graphic(&self) -> bool`

1.24.0[src]

Checks if the value is an ASCII graphic character: U+0021 '@' ... 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'%'; let space = b' '; let lf = b'\n'; let esc = 0x1b_u8; assert!(uppercase_a.is_ascii_graphic()); assert!(uppercase_g.is_ascii_graphic()); assert!(a.is_ascii_graphic()); assert!(g.is_ascii_graphic()); assert!(zero.is_ascii_graphic()); assert!(percent.is_ascii_graphic()); assert!(!space.is_ascii_graphic()); assert!(!lf.is_ascii_graphic()); assert!(!esc.is_ascii_graphic());Run

`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()); assert!(!a.is_ascii_control()); assert!(!g.is_ascii_control()); assert!(!zero.is_ascii_control()); assert!(!percent.is_ascii_control()); assert!(!space.is_ascii_control()); assert!(lf.is_ascii_control()); assert!(esc.is_ascii_control());Run
