It seems that the Rust programming language has
only been around for five years. “With all that’s going on in
the world you’d be forgiven for forgetting that as of today, it has been
five years since we released 1.0 in 2015! Rust has changed a lot these past
five years, so we wanted reflect back on all of our contributors’ work
since the stabilization of the language.“
