Rust clients for Rigetti APIs

This mono-repo contains three Rust crates:

• qcs-api-client-common: provides structures common to the gRPC and OpenAPI clients. In particular, it provides a ClientConfiguration type which is used to configure the clients using local QCS settings.
• qcs-api-client-grpc: provides a gRPC client for communicating with gRPC-based QCS APIs.
• qcs-api-client-openapi: provides a OpenAPI client for communicating with OpenAPI-based QCS APIs.

All crates are Apache-2.0.
