Expand description
Decodes a hex string into raw bytes.
Both, upper and lower case characters are valid in the input string and can
even be mixed (e.g. f9b4ca
, F9B4CA
and f9B4Ca
are all valid strings).
Example
assert_eq!(
hex::decode("48656c6c6f20776f726c6421"),
Ok("Hello world!".to_owned().into_bytes())
);
assert_eq!(hex::decode("123"), Err(hex::FromHexError::OddLength));
assert!(hex::decode("foo").is_err());
