Integer and bytes types can be compared using trait Eq. Some generated Rust structs can also have this property by deriving the Eq trait. Automatically derive Eq and Hash for: - messages that only have fields with integer or bytes types - messages where all field types also implement Eq and Hash - the Rust enum for one-of fields, where all fields implement Eq and Hash Generated code for Protobuf enums already derives Eq and Hash. BREAKING CHANGE: `prost-build` will automatically derive `trait Eq` and `trait Hash` for types where all field support those as well. If you manually `impl Eq` and/or `impl Hash` for generated types, then you need to remove the manual implementation. If you use `type_attribute` to `derive(Eq)` and/or `derive(Hash)`, then you need to remove those.
