The Rust Implementation of Apache RocketMQ auth

Overview

This module is mainly the implementation of the Apache RocketMQ auth, containing all the functionalities of the Java version rocketmq-auth.

Benchmarks

Run focused authentication and authorization hot-path benchmarks with:

cargo bench -p rocketmq-auth --bench auth_hot_path_bench

The benchmark covers remoting signature calculation, white remote address matching, ACL policy matching, and stateful authentication/authorization cache hits.

For CI or local regression gating, first verify the benchmark target compiles:

cargo test -p rocketmq-auth --benches --no-run

When collecting a baseline, run the benchmark on an otherwise idle machine and keep the generated Criterion report under target/criterion/auth_*. Compare future changes against the same toolchain and hardware; auth hot-path regressions should be investigated before merging changes that touch signing, whitelist matching, ACL policy matching, or stateful cache keys.
