Function safe_transmute::safe_transmute_one

pub fn safe_transmute_one<T: PodTransmutable>(bytes: &[u8]) -> Result<T, Error>

Transmute a byte slice into a single instance of a POD.

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does not have a memory alignment compatible with T. You will have to make a copy anyway, or modify how the data was originally made.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!(safe_transmute_one::<u32>(&[0x00, 0x00, 0x00, 0x01])?, 0x0100_0000);
