Function safe_transmute::transmute_one [−][src]
pub fn transmute_one<T: TriviallyTransmutable>(
bytes: &[u8]
) -> Result<T, Error<'_, u8, T>>
Transmute a byte slice into a single instance of a trivially transmutable type.
The byte slice must have at least enough bytes to fill a single instance of a type, extraneous data is ignored.
Errors
An error is returned in one of the following situations:
- The data does not have a memory alignment compatible with
T. You will have to make a copy anyway, or modify how the data was originally made. - The data does not have enough bytes for a single value
T.
Examples
// Little-endian assert_eq!(transmute_one::<u32>(&[0x00, 0x00, 0x00, 0x01])?, 0x0100_0000);
