# Primitive Type usize 1.0.0 [−]

The pointer-sized unsigned integer type.

See also the `std::usize` module.

However, please note that examples are shared between primitive integer types. So it's normal if you see usage of types like `isize` in there.

## Methods

### `impl usize`
[src]

#### `const fn min_value() -> usize`

Returns the smallest value that can be represented by this integer type.

# Examples

    assert_eq!(u8::min_value(), 0);Run

#### `fn wrapping_add(self, rhs: usize) -> usize`

#### `fn wrapping_div(self, rhs: usize) -> usize`
1.2.0

Wrapping (modular) division. Computes `self / other`. 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!(100u8.wrapping_div(10), 10);Run

#### `fn wrapping_rem(self, rhs: usize) -> usize`
1.2.0

Wrapping (modular) remainder. Computes `self % other`. Wrapped remainder 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.

# Examples

Basic usage:

    assert_eq!(100u8.wrapping_rem(10), 0);Run

#### `fn wrapping_neg(self) -> usize`
1.2.0

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.

# Examples

Basic usage:

    assert_eq!(100u8.wrapping_neg(), 156);
    assert_eq!(0u8.wrapping_neg(), 0);
    assert_eq!(180u8.wrapping_neg(), 76);
    assert_eq!(180u8.wrapping_neg(), (127 + 1) - (180u8 - (127 + 1)));Run

#### `fn wrapping_shl(self, rhs: u32) -> usize`
1.2.0

Panic-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!(1u8.wrapping_shl(7), 128);
    assert_eq!(1u8.wrapping_shl(8), 1);Run

#### `fn wrapping_shr(self, rhs: u32) -> usize`
1.2.0

Panic-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

Basic usage:

    assert_eq!(128u8.wrapping_shr(7), 1);
    assert_eq!(128u8.wrapping_shr(8), 128);Run

#### `fn overflowing_add(self, rhs: usize) -> (usize, bool)`
1.7.0

Calculates `self` + `rhs`

Returns a tuple of the addition along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

# Examples

Basic usage

    use std::u32;

    assert_eq!(5u32.overflowing_add(2), (7, false));
    assert_eq!(u32::MAX.overflowing_add(1), (0, true));Run

#### `fn overflowing_sub(self, rhs: usize) -> (usize, bool)`
1.7.0

Calculates `self` - `rhs`

Returns a tuple of the subtraction along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

# Examples

Basic usage

    use std::u32;

    assert_eq!(5u32.overflowing_sub(2), (3, false));
    assert_eq!(0u32.overflowing_sub(1), (u32::MAX, true));Run

#### `fn overflowing_mul(self, rhs: usize) -> (usize, bool)`
1.7.0

Calculates the multiplication of `self` and `rhs`.

Returns a tuple of the multiplication along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

# Examples

Basic usage

    assert_eq!(5u32.overflowing_mul(2), (10, false));
    assert_eq!(1_000_000_000u32.overflowing_mul(10), (1410065408, true));Run

#### `fn overflowing_div(self, rhs: usize) -> (usize, bool)`
1.7.0

Calculates 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`.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage

    assert_eq!(5u32.overflowing_div(2), (2, false));Run

#### `fn overflowing_rem(self, rhs: usize) -> (usize, bool)`
1.7.0

Calculates the remainder when `self` is divided by `rhs`.

Returns a tuple of the remainder 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`.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage

    assert_eq!(5u32.overflowing_rem(2), (1, false));Run

#### `fn overflowing_neg(self) -> (usize, bool)`
1.7.0

Negates 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!(0u32.overflowing_neg(), (0, false));
    assert_eq!(2u32.overflowing_neg(), (-2i32 as u32, true));Run

#### `fn overflowing_shl(self, rhs: u32) -> (usize, bool)`
1.7.0

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.

# Examples

Basic usage

    assert_eq!(0x10u32.overflowing_shl(4), (0x100, false));
    assert_eq!(0x10u32.overflowing_shl(36), (0x100, true));Run

#### `fn overflowing_shr(self, rhs: u32) -> (usize, bool)`
1.7.0

Shifts self right 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.

# Examples

Basic usage

    assert_eq!(0x10u32.overflowing_shr(4), (0x1, false));
    assert_eq!(0x10u32.overflowing_shr(36), (0x1, true));Run

#### `fn pow(self, exp: u32) -> usize`

Raises self to the power of `exp`, using exponentiation by squaring.

# Examples

Basic usage:

    assert_eq!(2u32.pow(4), 16);Run

#### `fn is_power_of_two(self) -> bool`

Returns `true` if and only if `self == 2^k` for some `k`.

# Examples

Basic usage:

    assert!(16u8.is_power_of_two());
    assert!(!10u8.is_power_of_two());Run

#### `fn next_power_of_two(self) -> usize`

Returns the smallest power of two greater than or equal to `self`.

When return value overflows (i.e. `self > (1 << (N-1))` for type `uN`), it panics in debug mode and return value is wrapped to 0 in release mode (the only situation in which method can return 0).

# Examples

Basic usage:

    assert_eq!(2u8.next_power_of_two(), 2);
    assert_eq!(3u8.next_power_of_two(), 4);Run

#### `fn checked_next_power_of_two(self) -> Option<usize>`

Returns the smallest power of two greater than or equal to `n`. If the next power of two is greater than the type's maximum value, `None` is returned, otherwise the power of two is wrapped in `Some`.

# Examples

Basic usage:

    assert_eq!(2u8.checked_next_power_of_two(), Some(2));
    assert_eq!(3u8.checked_next_power_of_two(), Some(4));
    assert_eq!(200u8.checked_next_power_of_two(), None);Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
