[−][src]Function safe_transmute::to_bytes::safe_transmute_one_to_bytes
pub fn safe_transmute_one_to_bytes<T: PodTransmutable>(from: &T) -> &[u8]
Transmute a single instance of a POD type into a slice of its bytes.
Examples
An u32
:
assert_eq!(safe_transmute_one_to_bytes(&0x0123_4567), &[0x67, 0x45, 0x23, 0x01]);
An arbitrary type:
#[repr(C)] #[derive(Clone, Copy)] struct Gene { x1: u8, x2: u8, } unsafe impl PodTransmutable for Gene {} assert_eq!(safe_transmute_one_to_bytes(&Gene { x1: 0x42, x2: 0x69, }), &[0x42, 0x69]);
