protoconv

Documentation

Overview

Package protoconv translates a small subset of protobuf (.proto) schemas into Cap'n Proto (.capnp) source, so capwrap users can author services in familiar proto syntax. Each unary `rpc M(Req) returns (Resp)` is flattened: the fields of Req/Resp become the Cap'n Proto method's params/results.

Supported: proto3, a service with unary rpc methods, and messages made of scalar/string/bytes fields. Streaming, repeated, map, oneof, enums and nested message fields are not supported and cause the affected method to be skipped.

func ToCapnp

func ToCapnp(src string) (capnp string, skipped []string, err error)

ToCapnp parses proto source and returns equivalent Cap'n Proto source. Skipped lists methods that could not be translated (with the reason).
