2.0.0

Added

• schema/0 to access the underlying definition of a message.

Changed

• Minimal supported Elixir version is now 1.15.
• BREAKING CHANGE: encoding functions now return the size alongside iodata. Previously, one had to use :binary.list_to_bin/1 to flatten the iodata and then use byte_size, defeating the purpose of having an iodata. Furthermore, it provides a significant performance boost.
• BREAKING CHANGE: Protox.decode! and Protox.decode no longer raise or return an error if a message don't have all required fields set. We should let the user decide whether it's a problem.
• BREAKING CHANGE: Rename InvalidFieldAttribute to InvalidFieldAttributeError for consistency.

Removed

• BREAKING CHANGE: Drop support of JSON encoding and decoding. The implementation was half-baked, it's preferable to have the library focused. Even Google doesn't recommend using JSON: "In short, there are many good reasons why Google prefers to use the standard wire format for virtually everything rather than ProtoJSON format".
• BREAKING CHANGE: Remove :path option in favor of the already existing :paths option, which covers the same functionality.
• BREAKING CHANGE: Remove :keep_unknown_fields option (the corresponding --keep-unknown-fields option for the mix task protox.generate is also removed). They are now always kept. It added complexity to the generation logic while not providing any value as one can simply ignore those fields and as it's mandatory to parse them correctly.
• BREAKING CHANGE: Remove generated defs/0 (functionality remains available through schema/0).
• BREAKING CHANGE: Remove generated field_def/1 (functionality remains available through schema/0).
• BREAKING CHANGE: Remove generated file_options/0 (functionality remains available through schema/0).
• BREAKING CHANGE: Remove generated required_fields/0 (functionality remains available through schema/0).
• BREAKING CHANGE: Remove generated syntax/0 (functionality remains available through schema/0).
• BREAKING CHANGE: Remove generated encode/1 from strings for enums.
• BREAKING CHANGE: Remove Protox.Encode.encode/1 and Protox.Encode.encode!/1 (functionality remains available in generated modules and in Protox).
