pub enum Endianness {
Little,
Big,
}
Enumerate for materializing the two kinds of machine byte order supported
by Rust.
Obtains this system's native endianness.
On this platform, the function returns Endianness::Little
.
Obtains Little Endian if and only if the given value is true
.
let data: &[u8] = &[4, 1];
let e = Endianness::le_iff(2 + 2 == 4);
assert_eq!(e.read_u16(data).unwrap(), 260);
let e = Endianness::le_iff(2 + 2 >= 5);
assert_eq!(e.read_u16(data).unwrap(), 1025);
Obtains Big Endian if and only if the given value is true
.
Examples
assert_eq!(Endianness::be_iff(2 + 2 == 4), Endianness::Big);
assert_eq!(Endianness::be_iff(2 + 2 >= 5), Endianness::Little);
Obtains the opposite endianness: Little Endian returns Big Endian and vice versa.
A type which can represent a byte order that is opposite to this one.
Converts the receiver into its opposite.
Checks whether this value represents the system's native endianness.
