Worked on the k2-fsa/sherpa-onnx repository to deliver proxy support for the downloader in the Rust binding, addressing deployment challenges in enterprise and CI/CD environments. The solution involved enabling the proxy-from-env feature in the ureq dependency and updating both Cargo.toml and build.rs to ensure the downloader respected standard proxy environment variables such as HTTP_PROXY, HTTPS_PROXY, and NO_PROXY. This approach streamlined build automation and dependency management, reducing the need for manual proxy configuration. The work demonstrated a focused application of Rust and build tooling to improve deployment reliability and align the project with common enterprise network requirements.
