This module contains the client and server stubs for Envoy's ext_proc protocol, generated and compiled for Rust, using Tonic as the gRPC implementation. These stubs are sufficient, if used with Tonic, to support a gRPC client or server that works with the ext_proc protocol.
The stubs build because they use git submodules in order to integrate with the four different GitHub repositories that house all the protobuf files needed to support the ext_proc protocol.
In order to build this crate, you'll need "protoc" installed on your machine. See the instructions.
