What this post added

This post details Meta's adoption and integration of the Rust programming language, tracing its journey from early use in source control (Mononoke) in 2016-2017, through wider adoption in developer tooling and small services (2017-2019), to dedicated support teams and significant contributions to projects like the Diem blockchain (2019-2020). It highlights the establishment of a Rust team in 2020 to focus on internal tooling, community contributions, C++/Rust interoperability, and engagement with the Rust Foundation.
