Enum byteordered::Endianness [−][src]
pub enum Endianness { Little, Big, }
Expand description
Enumerate for materializing the two kinds of machine byte order supported by Rust in a dynamic fashion. That is, the information of whether to read or write data in Little Endian or in Big Endian is resolved at run time by observing this value.
Using this type as the generic endianness type E
in a ByteOrdered
is useful when this information can only be retrieved
from a source that is unknown to the compiler.
Variants
Little Endian
Big Endian
Implementations
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
.
Examples
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.
