# Primitive Type usize1.0.0[−]

## Expand description

The pointer-sized unsigned integer type.

The size of this primitive is how many bytes it takes to reference any location in memory. For example, on a 32 bit target, this is 4 bytes and on a 64 bit target, this is 8 bytes.

## Implementations

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

RunShifts 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 = 0x6e10aausize;
let m = 0xaa00000000006e1;
assert_eq!(n.rotate_right(12), m);
```

RunReverses 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 = 0x1234567890123456usize;
let m = n.reverse_bits();
assert_eq!(m, 0x6a2c48091e6a2c48);
assert_eq!(0, 0usize.reverse_bits());
```

RunConverts an integer from big endian to the target’s endianness.

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

##### Examples

Basic usage:

```
let n = 0x1Ausize;
if cfg!(target_endian = "big") {
assert_eq!(usize::from_be(n), n)
} else {
assert_eq!(usize::from_be(n), n.swap_bytes())
}
```

RunConverts 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 = 0x1Ausize;
if cfg!(target_endian = "little") {
assert_eq!(usize::from_le(n), n)
} else {
assert_eq!(usize::from_le(n), n.swap_bytes())
}
```

RunUnchecked integer addition. Computes `self + rhs`

, assuming overflow
cannot occur.

##### Safety

This results in undefined behavior when
`self + rhs > usize::MAX`

or `self + rhs < usize::MIN`

,
i.e. when `checked_add`

would return `None`

.

Unchecked integer subtraction. Computes `self - rhs`

, assuming overflow
cannot occur.

##### Safety

This results in undefined behavior when
`self - rhs > usize::MAX`

or `self - rhs < usize::MIN`

,
i.e. when `checked_sub`

would return `None`

.

Unchecked integer multiplication. Computes `self * rhs`

, assuming overflow
cannot occur.

##### Safety

This results in undefined behavior when
`self * rhs > usize::MAX`

or `self * rhs < usize::MIN`

,
i.e. when `checked_mul`

would return `None`

.

Returns the logarithm of the number with respect to an arbitrary base, rounded down.

This method might not be optimized owing to implementation details;
`log2`

can produce results more efficiently for base 2, and `log10`

can produce results more efficiently for base 10.

##### Panics

When the number is negative, zero, or if the base is not at least 2; it panics in debug mode and the return value is 0 in release mode.

##### Examples

```
#![feature(int_log)]
assert_eq!(5usize.log(5), 1);
```

RunReturns the logarithm of the number with respect to an arbitrary base, rounded down.

Returns `None`

if the number is zero, or if the base is not at least 2.

This method might not be optimized owing to implementation details;
`checked_log2`

can produce results more efficiently for base 2, and
`checked_log10`

can produce results more efficiently for base 10.

##### Examples

```
#![feature(int_log)]
assert_eq!(5usize.checked_log(5), Some(1));
```

RunUnchecked shift left. Computes `self << rhs`

, assuming that
`rhs`

is less than the number of bits in `self`

.

##### Safety

This results in undefined behavior if `rhs`

is larger than
or equal to the number of bits in `self`

,
i.e. when `checked_shl`

would return `None`

.

Unchecked shift right. Computes `self >> rhs`

, assuming that
`rhs`

is less than the number of bits in `self`

.

##### Safety

This results in undefined behavior if `rhs`

is larger than
or equal to the number of bits in `self`

,
i.e. when `checked_shr`

would return `None`

.

Saturating addition with a signed integer. Computes `self + rhs`

,
saturating at the numeric bounds instead of overflowing.

assert_eq!((usize::MAX - 2).saturating_add_signed(4), usize::MAX);
```

RunWrapping (modular) multiplication. Computes `self * rhs`

, wrapping around at the boundary of the type.

##### Examples

Basic usage:

Please note that this example is shared between integer types.
Which explains why `u8`

is used here.

```
assert_eq!(10u8.wrapping_mul(12), 120);
assert_eq!(25u8.wrapping_mul(12), 44);
```

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

.
Wrapped division on unsigned types is just normal division.
There’s no way wrapping could ever happen.
This function exists, so that all operations
are accounted for in the wrapping operations.

##### Examples

Basic usage:

`assert_eq!(100usize.wrapping_div(10), 10);`

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

.
Wrapped division on unsigned types is just normal division.
There’s no way wrapping could ever happen.
This function exists, so that all operations
are accounted for in the wrapping operations.
Since, for the positive integers, all common
definitions of division are equal, this
is exactly equal to `self.wrapping_div(rhs)`

.

##### Examples

Basic usage:

`assert_eq!(100usize.wrapping_div_euclid(10), 10);`

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

.

are accounted for in the wrapping operations.

##### Examples

Basic usage:

`assert_eq!(100usize.wrapping_rem(10), 0);`

RunWrapping Euclidean modulo. Computes `self.rem_euclid(rhs)`

.
Wrapped modulo calculation on unsigned types is
just the regular remainder calculation.
There’s no way wrapping could ever happen.
This function exists, so that all operations
are accounted for in the wrapping operations.
Since, for the positive integers, all common
definitions of division are equal, this
is exactly equal to `self.wrapping_rem(rhs)`

.

##### Examples

Basic usage:

`assert_eq!(100usize.wrapping_rem_euclid(10), 0);`

RunWrapping (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.

##### Examples

Basic usage:

Please note that this example is shared between integer types.
Which explains why `i8`

is used here.

```
assert_eq!(100i8.wrapping_neg(), -100);
assert_eq!((-128i8).wrapping_neg(), -128);
```

RunPanic-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.

##### Examples

Basic usage:

```
assert_eq!(1usize.wrapping_shl(7), 128);
assert_eq!(1usize.wrapping_shl(128), 1);
```

RunPanic-free bitwise shift-right; 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-right; the
RHS of a wrapping shift-right 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_right`

function,
which may be what you want instead.

##### Examples

assert_eq!(128usize.wrapping_shr(7), 1);
assert_eq!(128usize.wrapping_shr(128), 128);
```

RunCalculates `self`

+ `rhs`

##### Examples

Basic usage

```
assert_eq!(5usize.overflowing_add(2), (7, false));
assert_eq!(usize::MAX.overflowing_add(1), (0, true));
```

RunCalculates `self + rhs + carry`

without the ability to overflow.

Performs “ternary addition” which takes in an extra bit to add, and may return an additional bit of overflow. This allows for chaining together multiple additions to create “big integers” which represent larger values.

This can be thought of as a 64-bit “full adder”, in the electronics sense.

##### Examples

Basic usage

```
#![feature(bigint_helper_methods)]

assert_eq!(usize::MAX.carrying_add(1, true), (1, true));
assert_eq!(usize::MAX.carrying_add(usize::MAX, true), (usize::MAX, true));
```

RunIf `carry`

is false, this method is equivalent to `overflowing_add`

:

```
#![feature(bigint_helper_methods)]
assert_eq!(5_usize.carrying_add(2, false), 5_usize.overflowing_add(2));
assert_eq!(usize::MAX.carrying_add(1, false), usize::MAX.overflowing_add(1));
```

assert_eq!(1usize.overflowing_add_signed(-2), (usize::MAX, true));
assert_eq!((usize::MAX - 2).overflowing_add_signed(4), (1, true));
```

```

RunCalculates the divisor when `self`

is divided by `rhs`

.

Returns a tuple of the divisor 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`

is exactly equal to `self.overflowing_rem(rhs)`

.

is 0.

##### Examples

Basic usage

`assert_eq!(5usize.overflowing_rem_euclid(2), (1, false));`

RunNegates self in an overflowing fashion.

Returns `!self + 1`

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

##### Examples

Basic usage

```
assert_eq!(0usize.overflowing_neg(), (0, false));
assert_eq!(2usize.overflowing_neg(), (-2i32 as usize, true));
```

RunShifts 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.

.

When return value overflows (i.e., `self > (1 << (N-1))`

for type
`uN`

), it panics in debug mode and the return value is wrapped to 0 in
release mode (the only situation in which method can return 0).

Calculates the complete product `self * rhs`

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.

##### Examples

Basic usage:

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

is used here.

```
#![feature(bigint_helper_methods)]
assert_eq!(5u32.widening_mul(2), (10, 0));
assert_eq!(1_000_000_000u32.widening_mul(10), (1410065408, 2));
```

RunCalculates 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.

##### Examples

Basic usage:

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

is used here.

```
#![feature(bigint_helper_methods)]
assert_eq!(5u32.carrying_mul(2, 0), (10, 0));
assert_eq!(5u32.carrying_mul(2, 10), (20, 0));

assert_eq!(usize::MAX.carrying_mul(usize::MAX, usize::MAX), (0, usize::MAX));
```

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,
789_u16.wrapping_mul(456).wrapping_add(123),
