pub fn decode(code: &str) -> Result<CheatPatch, CheatError>Expand description
Decode code as a Game Genie code, falling back to Pro Action Replay only when code
doesn’t match the Game Genie shape at all.
The two formats’ valid shapes never overlap (9 characters with a dash vs. exactly 8 hex
digits), so this dispatch is unambiguous. Only CheatError::UnrecognizedFormat falls
through to the Pro Action Replay decoder — a Game Genie–shaped code with a genuinely invalid
character (e.g. C282-070G) returns that specific CheatError::InvalidCharacter instead
of a misleading “wrong format” from a decoder that was never going to match its shape either.
§Errors
Returns the CheatError from whichever format code’s length suggests; if neither format
recognizes the shape at all, returns CheatError::UnrecognizedFormat.
