Ask HN: What are you using Rust for in production?
Also interested in knowing if the project is green field or rewrite. If rewriten, what language were you replacing?
* Progressively introduce Rust instead of replacing entire applications (Rust really shines in this area)
* Leverage node's strong HTTP and routing story while waiting for this to stabilize in Rust
* Leverage existing tooling for APM, config management, etc.
For example, one middleware verifies the request body with a signature from a header. Another one parses the body from a `Buffer` to JSON, transforms, and serializes as protobuf.
