## Implementations

source### impl i8

### impl i8

source#### pub fn from_str_radix(src: &str, radix: u32) -> Result<Self, ParseIntError>

#### pub fn from_str_radix(src: &str, radix: u32) -> Result<Self, ParseIntError>

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

The string is expected to be an optional `+`

or `-`

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!(i8::from_str_radix("A", 16), Ok(10));`

1.2.0 (const: 1.52.0) · source#### pub const fn wrapping_div(self, rhs: Self) -> Self

#### pub const fn wrapping_div(self, rhs: Self) -> Self

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

, wrapping around at the
boundary of the type.

The only case where such wrapping can occur is when one divides `MIN / -1`

on a signed type (where
`MIN`

is the negative minimal value for the type); this is equivalent to `-MIN`

, a positive value
that is too large to represent in the type. In such a case, this function returns `MIN`

itself.

##### Panics

This function will panic if `rhs`

is 0.

##### Examples

Basic usage:

```
assert_eq!(100i8.wrapping_div(10), 10);
assert_eq!((-128i8).wrapping_div(-1), -128);
```

Run1.38.0 (const: 1.52.0) · source#### pub const fn wrapping_div_euclid(self, rhs: Self) -> Self

#### pub const fn wrapping_div_euclid(self, rhs: Self) -> Self

Wrapping Euclidean division. Computes `self.div_euclid(rhs)`

,
wrapping around at the boundary of the type.

Wrapping will only occur in `MIN / -1`

on a signed type (where `MIN`

is the negative minimal value
for the type). This is equivalent to `-MIN`

, a positive value that is too large to represent in the
type. In this case, this method returns `MIN`

itself.

##### Panics

This function will panic if `rhs`

is 0.

##### Examples

Basic usage:

```
assert_eq!(100i8.wrapping_div_euclid(10), 10);
assert_eq!((-128i8).wrapping_div_euclid(-1), -128);
```

Run1.2.0 (const: 1.52.0) · source#### pub const fn wrapping_rem(self, rhs: Self) -> Self

#### pub const fn wrapping_rem(self, rhs: Self) -> Self

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

, wrapping around at the
boundary of the type.

Such wrap-around never actually occurs mathematically; implementation artifacts make `x % y`

invalid for `MIN / -1`

on a signed type (where `MIN`

is the negative minimal value). In such a case,
this function returns `0`

.

##### Panics

This function will panic if `rhs`

is 0.

##### Examples

Basic usage:

```
assert_eq!(100i8.wrapping_rem(10), 0);
assert_eq!((-128i8).wrapping_rem(-1), 0);

Run1.38.0 (const: 1.52.0) · source#### pub const fn wrapping_rem_euclid(self, rhs: Self) -> Self

, wrapping around
at the boundary of the type.

Wrapping will only occur in `MIN % -1`

on a signed type (where `MIN`

is the negative minimal value
for the type). In this case, this method returns 0.

##### Panics

The only case where such wrapping can occur is when one negates `MIN`

on a signed type (where `MIN`

is the negative minimal value for the type); this is a positive value that is too large to represent

Run1.2.0 (const: 1.32.0) · source#### pub const fn wrapping_shl(self, rhs: u32) -> Self

#### pub const fn wrapping_shl(self, rhs: u32) -> Self

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.

Basic usage:

assert_eq!((-1i8).wrapping_shl(128), -1);

Note that this is *not* the same as a rotate-right; the RHS of a wrapping shift-right is restricted

Wrapping (modular) absolute value. Computes `self.abs()`

the boundary of the type.

The only case where such wrapping can occur is when one takes the absolute value of the negative
minimal value for the type; this is a positive value that is too large to represent in the type. In
such a case, this function returns `MIN`

itself.

#### pub const fn overflowing_rem_euclid(self, rhs: Self) -> (Self, bool)

Overflowing Euclidean remainder. Calculates `self.rem_euclid(rhs)`

.

Returns a tuple of the remainder after dividing along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would occur then 0 is returned.

##### Panics

This function will panic if `rhs`

is 0.

##### Examples

Basic usage:

```

assert_eq!(i8::MIN.overflowing_rem_euclid(-1), (0, true));
```

Run1.7.0 (const: 1.32.0) · source#### pub const fn overflowing_neg(self) -> (Self, bool)

#### pub const fn overflowing_neg(self) -> (Self, bool)

Negates self, overflowing if this is equal to the minimum value.

Returns a tuple of the negated version of self along with a boolean indicating whether an overflow
happened. If `self`

is the minimum value (e.g., `i32::MIN`

for values of type `i32`

), then the
minimum value will be returned again and `true`

will be returned for an overflow happening.

##### Examples

Basic usage:

```
assert_eq!(2i8.overflowing_neg(), (-2, false));
assert_eq!(i8::MIN.overflowing_neg(), (i8::MIN, true));
```

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:

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

.

Returns a tuple of the absolute version of self along with a boolean indicating whether an overflow happened. If self is the minimum value (e.g., i8::MIN for values of type i8), then the minimum value will be returned again and true will be returned for an overflow happening.

##### Examples

Basic usage:

```
assert_eq!(10i8.overflowing_abs(), (10, false));

1.38.0 (const: 1.52.0) · source#### pub const fn div_euclid(self, rhs: Self) -> Self

#### pub const fn div_euclid(self, rhs: Self) -> Self

Calculates the quotient of Euclidean division of `self`

by `rhs`

.

This computes the integer `q`

such that `self = q * rhs + r`

, with
`r = self.rem_euclid(rhs)`

and `0 <= r < abs(rhs)`

.

In other words, the result is `self / rhs`

rounded to the integer `q`

such that `self >= q * rhs`

.
If `self > 0`

, this is equal to round towards zero (the default in Rust);
if `self < 0`

, this is equal to round towards +/- infinity.

##### Panics

This function will panic if `rhs`

is 0 or the division results in overflow.

##### Examples

Basic usage:

```
let a: i8 = 7; // or any other integer type
let b = 4;
assert_eq!(a.div_euclid(b), 1); // 7 >= 4 * 1
assert_eq!(a.div_euclid(-b), -1); // 7 >= -4 * -1

```
