Currently we rely on the inner bytes with types that are passed across the FFI boundry when implementing comparison functions (e.g. `Ord`, `PartialEq`), this is incorrect because the bytes are opaque, meaning the byte layout is not guaranteed across versions of `libsecp26k1`. Implement stable comparison functionality by doing: - Implement `core::cmp` traits by first coercing the data into a stable form e.g., by serializing it. - Add fast comparison methods to `secp256k1-sys` types that wrap types from libsecp, add similar methods to types in `secp256k1` that wrap `secp256k1-sys` types (just call through to inner type). - In `secp256k1-sys` feature gate the new `core::cmp` impls on `not(fuzzing)`, when fuzzing just derive the impls instead. Any additional methods added to `secp256k1-sys` types are private, justified by the fact the -sys is meant to be just a thin wrapper around libsecp256k1, we don't want to commit to supporting additional API functions. Please note, the solution presented in this patch is already present for `secp256k1::PublicKey`, this PR removes that code in favour of deriving traits that then call down to the same logic in `secp256k1-sys`. |
