Implementations
sourceimpl Endianness
impl Endianness
sourcepub fn native() -> Self
pub fn native() -> Self
Obtains this system’s native endianness.
On this platform, the function returns Endianness::Little
.
sourcepub fn le_iff(e: bool) -> Self
pub fn le_iff(e: bool) -> Self
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);
sourcepub fn be_iff(e: bool) -> Self
pub fn be_iff(e: bool) -> Self
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);
sourcepub fn to_opposite(self) -> Self
pub fn to_opposite(self) -> Self
Obtains the opposite endianness: Little Endian returns Big Endian and vice versa.
