impl u128
1.0.0 · sourcepub 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.

Panic-free bitwise shift-left; yields self << mask(rhs)

being returned to the other end. The primitive integer
types all implement a rotate_left

1.38.0 (const: 1.52.0) · sourcepub const fn rem_euclid(self, rhs: Self) -> Self
pub const fn rem_euclid(self, rhs: Self) -> Self
Calculates the least remainder of self (mod rhs)
.
Since, for the positive integers, all common
definitions of division are equal, this
is exactly equal to self % rhs
.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage:
assert_eq!(7u128.rem_euclid(4), 3); // or any other integer type
Runsourcepub const fn div_ceil(self, rhs: Self) -> Self
pub const fn div_ceil(self, rhs: Self) -> Self
Calculates the quotient of self

, rounding the result towards positive infinity.
Panics
This function will panic if rhs
is zero.
Overflow behavior
On overflow, this function will panic if overflow checks are enabled (default in debug mode) and wrap if overflow checks are disabled (default in release mode).
Examples
Basic usage:
#![feature(int_roundings)]
assert_eq!(7_u128.div_ceil(4), 2);
