Assertion
The early Rust compiler was written in OCaml before transitioning to a self-hosting compiler. The team removed Rust's garbage collector by 2013, after which programs written in Rust ran even faster.
Quote
As the team improved the memory-management system, Rust had increasingly little need for its own garbage collector—and by 2013, the team had removed it. Programs written in Rust would now run even faster: no periodic halts while the computer performed cleanup.
