Utilities for encoding and decoding hex strings.

To encode a &[u8] you can use:

• [encode]
• [encode_to_vec]

To decode you can use:

• [decode] for &str
• [decode_from_vec] for Vec<u8>
• [FromHex::from_hex] for Vec<u8> and some u8 array sizes.
• [decode_to_buf] for decoding a &str into a &mut [u8] with the exact size.

Features

serde

With the serde feature enabled you can use [crate::serde] to serialize any u8 array or Vec<u8> to hex and deserialize hex string to a Vec<u8> and a fixed selection of u8 arrays.
