# Architecture
This section describes how RustStream is built and what its design costs a service.
- [Benchmarks](benchmarks.md): what the framework costs over a raw client, and the cost of its
own code.
- [Broker authors](../broker-authors/index.md): the contract a broker crate implements, and the
conformance suites that check it.
