Good example of high performance Rust project without unsafe code?

I’ve been using Rust for a while now and even though I like it a lot I find it rather difficult to achieve similar performance to C code without the use of unsafe code which kind of (not fully) defeats the purpose of Rust (imo).

Does anyone know about any projects (re)written in Rust that are equal in performance to the C version without the use of unsafe code? Perhaps some compression or image library?
