Implementations

impl Endianness

pub fn native() -> Self

Obtains this system’s native endianness.

On this platform, the function returns Endianness::Little.

pub fn le_iif(e: bool) -> Self

Obtains Little Endian if and only if the given value is true.

Examples

assert_eq!(Endianness::le_iif(2 + 2 == 4), Endianness::Little);
assert_eq!(Endianness::le_iif(2 + 2 >= 5), Endianness::Big);

pub fn be_iif(e: bool) -> Self

Obtains Big Endian if and only if the given value is true.

Examples

assert_eq!(Endianness::be_iif(2 + 2 == 4), Endianness::Big);
assert_eq!(Endianness::be_iif(2 + 2 >= 5), Endianness::Little);

pub fn to_opposite(self) -> Self

Obtains the opposite endianness: Little Endian returns Big Endian and vice versa.
