# Primitive Type usize [−]

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`

#### `const fn min_value() -> usize`
1.0.0

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

# Examples

#### `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

    assert_eq!(100u8.wrapping_div(10), 10);

#### `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

#### `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:

fn main() { 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))); }

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

#### `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:

fn main() { assert_eq!(1u8.wrapping_shl(7), 128); assert_eq!(1u8.wrapping_shl(8), 1); }

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

#### `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:

fn main() { assert_eq!(128u8.wrapping_shr(7), 1); assert_eq!(128u8.wrapping_shr(8), 128); }

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

    assert_eq!(5u32.overflowing_mul(2), (10, false));

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

## 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`)
