usize - Rust
Description: API documentation for the Rust `usize` primitive in crate `std`.
Keywords: rust, rustlang, rust-lang, usize

# Primitive Type usize 1.0.0[−]

The pointer-sized unsigned integer type.

See also the `std::usize` module.

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.

## Methods

###

`impl usize`

[src]

####

`pub const fn min_value() -> usize`

[src]

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

# Examples

Basic usage:

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

####

`pub const fn max_value() -> usize`

[src]

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

# Examples

Basic usage:

    assert_eq!(usize::max_value(), 18446744073709551615);Run

####

`pub fn from_str_radix(src: &str, radix: u32) -> Result<usize, ParseIntError>`

[src]

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));Run

####

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

`pub fn rotate_right(self, n: u32) -> usize`

[src]

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 `>>`!

# Examples

Basic usage:

Please note that this example is shared between integer types. Which explains why `u64` is used here.

`pub fn wrapping_neg(self) -> usize`

1.2.0
[src]

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:

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

####

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

1.2.0
[src]

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

####

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

1.2.0
[src]

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.

`pub fn next_power_of_two(self) -> usize`

[src]

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

####

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

[src]

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!(2usize.checked_next_power_of_two(), Some(2));
    assert_eq!(3usize.checked_next_power_of_two(), Some(4));
    assert_eq!(usize::max_value().checked_next_power_of_two(), None);Run

####

`pub fn wrapping_next_power_of_two(self) -> usize`

[src]

🔬 This is a nightly-only experimental API. (`wrapping_next_power_of_two` #32463)

needs decision on wrapping behaviour

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, the return value is wrapped to `0`.

# Examples

Basic usage:

    #![feature(wrapping_next_power_of_two)]

    assert_eq!(2usize.wrapping_next_power_of_two(), 2);
    assert_eq!(3usize.wrapping_next_power_of_two(), 4);
    assert_eq!(usize::max_value().wrapping_next_power_of_two(), 0);Run

`pub fn to_bytes(self) -> [u8; 8]`

[src]

🔬 This is a nightly-only experimental API. (`int_to_from_bytes` #49792)

Return the memory representation of this integer as a byte array.

The target platform’s native endianness is used. Portable code likely wants to use this after `to_be` or `to_le`.

# Examples

    #![feature(int_to_from_bytes)]

    let bytes = 0x1234_5678_u32.to_be().to_bytes();
    assert_eq!(bytes, [0x12, 0x34, 0x56, 0x78]);Run

####

`pub fn from_bytes(bytes: [u8; 8]) -> usize`

[src]

🔬 This is a nightly-only experimental API. (`int_to_from_bytes` #49792)

Create an integer value from its memory representation as a byte array.

The target platform’s native endianness is used. Portable code likely wants to use `to_be` or `to_le` after this.

# Examples

    #![feature(int_to_from_bytes)]

    let int = u32::from_be(u32::from_bytes([0x12, 0x34, 0x56, 0x78]));
    assert_eq!(int, 0x1234_5678_u32);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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
