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)`

without modifying the original"]pub const fn overflowing_rem(self, rhs: u8) -> (u8, bool)
```

1.7.0 (const: 1.52.0)[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!(5u8.overflowing_rem(2), (1, false));Run

```
#[must_use =
"this returns the result of the operation, \
without modifying the original"]pub const fn overflowing_rem_euclid(self, rhs: u8) -> (u8, bool)
```

1.38.0 (const: 1.52.0)[src]

Calculates the remainder `self.rem_euclid(rhs)`

as if by Euclidean division.

Returns a tuple of the modulo 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`

.
Since, for the positive integers, all common
definitions of division are equal, this operation
is exactly equal to `self.overflowing_rem(rhs)`

.

# Panics

This function will panic if `rhs`

is 0.

# Examples

Basic usage

assert_eq!(5u8.overflowing_rem_euclid(2), (1, false));Run

1.7.0 (const: 1.32.0)[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!(0u8.overflowing_neg(), (0, false)); assert_eq!(2u8.overflowing_neg(), (-2i32 as u8, true));Run

```

1.7.0 (const: 1.32.0)[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.

# Examples

`pub const fn to_ne_bytes(self) -> [u8; 1]`

1.32.0 (const: 1.44.0)[src]

Return the memory representation of this integer as a byte array in native byte order.

As the target platform’s native endianness is used, portable code
should use `to_be_bytes`

1.32.0 (const: 1.44.0)[src]

Create a native endian integer value from its memory representation as a byte array in native endianness.

As the target platform’s native endianness is used, portable code

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

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

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
