Function encode_to_str 

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

Encodes input as a hex string using lowercase characters into a mutable slice of bytes output. Returns the slice to output reinterpreted as str.

Errors

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

Examples

let mut bytes = [0u8; 4 * 2];
let s = const_hex::encode_to_str(b"kiwi", &mut bytes)?;
assert_eq!(s, "6b697769");
