Implementations§
source§impl u64
impl u64
sourcepub fn from_str_radix(src: &str, radix: u32) -> Result<u64, ParseIntError>
pub fn from_str_radix(src: &str, radix: u32) -> Result<u64, 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!(u64::from_str_radix("A", 16), Ok(10));
Runconst: 1.32.0 · sourcepub const fn count_ones(self) -> u32
pub const fn count_ones(self) -> u32
const: 1.32.0 · sourcepub const fn count_zeros(self) -> u32
pub const fn count_zeros(self) -> u32
const: 1.32.0 · sourcepub const fn leading_zeros(self) -> u32
pub const fn leading_zeros(self) -> u32
Returns the number of leading zeros in the binary representation of self
.
Depending on what you’re doing with the value, you might also be interested in the
ilog2
function which returns a consistent number, even if the type widens.
§Examples
Basic usage:
let n = u64::MAX >> 2;
assert_eq!(n.leading_zeros(), 2);

Shifts the bits to the right by a specified amount, n
,
wrapping the truncated bits to the beginning of the resulting
integer.
Please note this isn’t the same operation as the >>
shifting operator!
§Examples

§Examples
Basic usage:

Since unsigned types do not have negative equivalents
all applications of this function will wrap (except for -0

pub fn carrying_add(self, rhs: u64, carry: bool) -> (u64, bool)
bigint_helper_methods
#85532)Calculates self
+ rhs
+ carry
and returns a tuple containing
the sum and the output carry.
Performs “ternary addition” of two integer operands and a carry-in bit, and returns an output integer and a carry-out bit. This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition.
This can be thought of as a 64-bit “full adder”, in the electronics sense.
If the input carry is false, this method is equivalent to
overflowing_add
, and the output carry is
equal to the overflow flag. Note that although carry and overflow
flags are similar for unsigned integers, they are different for
signed integers.
