# Primitive Type u64

1.0.0 ·## Expand description

The 64-bit unsigned integer type.

## Implementations§

source§### impl u64

### impl u64

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!(u64::from_str_radix("A", 16), Ok(10));`

Runconst: 1.32.0 · source#### pub const fn count_ones(self) -> u32

#### pub const fn count_ones(self) -> u32

#### pub const fn count_zeros(self) -> u32

const: 1.32.0 · source#### pub 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);
```

const: 1.32.0 · source#### pub const fn rotate_right(self, n: u32) -> Self

#### pub const fn rotate_right(self, n: u32) -> Self

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

Basic usage:

```
let n = 0x6e10aau64;
let m = 0xaa00000000006e1;
assert_eq!(n.rotate_right(12), m);

1.37.0 (const: 1.37.0) · source#### pub const fn reverse_bits(self) -> Self

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

Reverses the order of bits in the integer. The least significant bit becomes the most significant bit, second least-significant bit becomes second most-significant bit, etc.

##### Examples

Basic usage:

```
let n = 0x1234567890123456u64;
let m = n.reverse_bits();
assert_eq!(m, 0x6a2c48091e6a2c48);
assert_eq!(0, 0u64.reverse_bits());
```

Runconst: 1.32.0 · source#### pub const fn from_le(x: Self) -> Self

#### pub const fn from_le(x: Self) -> Self

Converts an integer from little endian to the target’s endianness.

On little endian this is a no-op. On big endian the bytes are swapped.

##### Examples

Basic usage:

```
let n = 0x1Au64;
if cfg!(target_endian = "little") {
assert_eq!(u64::from_le(n), n)
} else {
assert_eq!(u64::from_le(n), n.swap_bytes())
}

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`

).

#85532)Calculates `self`

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.

`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.

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

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)`

.

is 0.

that represents the negation of this unsigned value. Note that for
positive unsigned values overflow always occurs, but negating 0 does
not overflow.

##### Examples

Shifts self left by `rhs`

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

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

If you also need to add a carry to the wide result, then you want

`bigint_helper_methods`

#85532)Calculates the “full multiplication” `self * rhs + carry`

without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you don’t need the `carry`

, then you can use `Self::widening_mul`

instead.

##### Examples

Basic usage:

Please note that this example is shared between integer types.
Which explains why `u32`

is used here.

scalar_mul_eq(&mut v, 0xFEED);
assert_eq!(v, [0xE38D, 0xD159, 0x86D3]);
```

RunIf `carry`

is zero, this is similar to `overflowing_mul`

,
except that it gives the value of the overflow instead of just whether one happened:

```
#![feature(bigint_helper_methods)]
let r = u8::carrying_mul(7, 13, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(7, 13));
let r = u8::carrying_mul(13, 42, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(13, 42));
```

RunThe value of the first field in the returned tuple matches what you’d get
by combining the `wrapping_mul`

and
`wrapping_add`

methods:

```
#![feature(bigint_helper_methods)]
assert_eq!(
789_u16.carrying_mul(456, 123).0,
