Go(lang) APIs for the Timeless Stack (📖 docs here.
These APIs include all message type definitions, message and error enums, and serialization glue for the APIs for projects like rio, repeatr, and hitch.
Function definitions for some RPC APIs are also exported. Generally you will be able to find implementations of these func APIs in each project, and also a package which exports the same funcs again, but works via an exec layer and RPC protocol.
