Enum nifti::Endianness [−][src]
pub enum Endianness { Little, Big, }
Expand description
Enumerate for materializing the two kinds of machine byte order supported by Rust.
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.
Trait Implementations
type Opposite = Endianness
type Opposite = Endianness
A type which can represent a byte order that is opposite to this one.
Converts the receiver into its opposite.

Checks if self
is actually part of its subset T
(and can be converted to it).
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
