Rust is foundational to the Linkerd project’s technology roadmap. Its type system allows us to build modular, testable, composable units without sacrificing runtime performance. What’s been most surprising, though, is how Rust’s lifetime/borrow checking system allows us to avoid large classes of resource leaks. After 2 years, I really can ...
