pub fn encode_to_slice_upper<T: AsRef<[u8]>>(
    input: T,
    output: &mut [u8],
) -> Result<(), FromHexError>

Encodes input as a hex string using uppercase characters into a mutable slice of bytes output.

Errors

If the output buffer is not exactly input.len() * 2 bytes long.

Examples

let mut bytes = [0u8; 4 * 2];
const_hex::encode_to_slice_upper(b"kiwi", &mut bytes)?;
assert_eq!(&bytes, b"6B697769");
