Protocol Buffers - Google's data interchange format (grpc依赖) https://developers.google.com/protocol-buffers/

Tag: Branch: Tree: 51cf616dab

Chris Fallin 87a18f3774 Support oneof defs in upb. This change adds support for a OneofDef (upb_oneofdef), which represents a 'oneof' as introduced by Protocol Buffers. This is semantically a union type that contains fields and in turn may be added to a MessageDef. This change does not alter parsing or the handler abstraction in any way, because a oneof has impact only at a higher semantic level (i.e., any sort of storage of the fields in a message object), which is user-specific with respect to upb.		10 years ago

Ruby extension

To build, run (from the top upb directory):

$ make ruby
$ sudo make install

To test, run:

$ make rubytest

The binding currently supports:

- loading message types from descriptors.
- constructing message instances
- reading and writing their members
- parsing and serializing the messages
- all data types (including nested and repeated)

The binding does not currently support:

- defining message types directly in Ruby code.
- generating Ruby code for a .proto file.
- type-checking for setters
- homogenous / type-checked arrays
- default values

Because code generation is not currently implemented, the interface to import a specific message type is kind of clunky for the moment.
