Pretty happy to have gotten a larger contribution in for an open source project, (Avro library for Rust.) I've contributed some one-line fixes to projects here and there, but this was a first for me in making a sizeable change and working through the reviews to get it to where it can be merged. Now, (in v0.18.0,) the Rust Avro library is around 5x faster when directly writing serde-serializable values, and has a fix for occasional issues where written messages didn't adhere strictly to the provided schema.
