Crate hex

Encoding and decoding hex strings.

For most cases, you can simply use the decode, encode and encode_upper functions. If you need a bit more control, use the traits ToHex and FromHex instead.

Example

let hex_string = hex::encode("Hello world!");

println!("{}", hex_string); // Prints "48656c6c6f20776f726c6421"
