Which Rust programs are original, not a rewrite of some other software?

Outside of the Rust compiler and tooling, of course.

Lately, I see more and more software being rewritten in Rust for speed.

I myself absolutely love Rust, have been working with it since 2021, and intend to stick with it. But somehow Rust projects in my bubble seem to be obsessed with speed and are rewrites of something that had existed before. I'm struggling to name examples of novel products that would be looking for a PMF that would be written in Rust from the start.

As an example, currently astral.sh is rewriting the whole stack of Python build tools in Rust. I like what they are doing, but this just reinforces the point above.

As another example, reth is a rewrite of Ethereum client, a handful of which had existed before.
