1.0.0[−]Primitive Type usize
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.

Since unsigned types do not have negative equivalents
all applications of this function will wrap (except for -0).

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.

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.

instead.
Examples
let bytes = 0x12345678usize.to_ne_bytes(); assert_eq!(bytes, if cfg!(target_endian = "big") { [0x12, 0x34, 0x56, 0x78] } else { [0x78, 0x56, 0x34, 0x12] });Run
pub fn from_be_bytes(bytes: [u8; 4]) -> usize1.32.0[src]
pub fn from_be_bytes(bytes: [u8; 4]) -> usizeCreate an integer value from its representation as a byte array in big endian.
Examples
let value = usize::from_be_bytes([0x12, 0x34, 0x56, 0x78]); assert_eq!(value, 0x12345678);Run
When starting from a slice rather than an array, fallible conversion APIs can be used:
#![feature(try_from)] use std::convert::TryInto; fn read_be_usize(input: &mut &[u8]) -> usize { let (int_bytes, rest) = input.split_at(std::mem::size_of::<usize>()); *input = rest; usize::from_be_bytes(int_bytes.try_into().unwrap()) }Run
pub fn from_le_bytes(bytes: [u8; 4]) -> usize1.32.0[src]
pub fn from_le_bytes(bytes: [u8; 4]) -> usizeCreate an integer value from its representation as a byte array in little endian.
Examples
let value = usize::from_le_bytes([0x78, 0x56, 0x34, 0x12]); assert_eq!(value, 0x12345678);Run
When starting from a slice rather than an array, fallible conversion APIs can be used:
#![feature(try_from)] use std::convert::TryInto; fn read_be_usize(input: &mut &[u8]) -> usize { let (int_bytes, rest) = input.split_at(std::mem::size_of::<usize>()); *input = rest; usize::from_be_bytes(int_bytes.try_into().unwrap()) }Run
pub fn from_ne_bytes(bytes: [u8; 4]) -> usize1.32.0[src]
pub fn from_ne_bytes(bytes: [u8; 4]) -> usizeCreate an integer value from its memory representation as a byte array in native endianness.
As the target platform's native endianness is used, portable code
likely wants to use from_be_bytes or from_le_bytes, as
appropriate instead.
Examples
let value = usize::from_ne_bytes(if cfg!(target_endian = "big") { [0x12, 0x34, 0x56, 0x78] } else { [0x78, 0x56, 0x34, 0x12] }); assert_eq!(value, 0x12345678);Run
