### impl u128

1.0.0 · 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 `+`

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!(u128::from_str_radix("A", 16), Ok(10));`

#### pub const fn wrapping_neg(self) -> Self

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.

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`

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

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.
