I had a pretty good time rewriting various coreutils in Rust. I liked it because the difficulty of doing so ranges from something as easy as the true command, where you simply exit with a success status, to more challenging stuff like writing a basic shell.
Granted, it's not that complicated to write CLIs with simple inputs and outputs, so maybe it's not valuable for others but it certainly helped me understand Rust better than before.
I am also thinking about making an IRC bot in Rust but I don't have enough experience to do so yet

When I'm curious about a language, I usually first build some implementation of a perceptron or basic neural network, as well as a (usually very bad) text editor.
I feel like once I have those behind me, I've got some fundamentals and can dive deeper into what makes the specific language actually special :)
perhaps a simple turn based card game with the ability to add custom cards
Turn the Fibonacci series into an Iterator. >:)
that could be a good exercise, I haven't got the needed knowledge to do so, but I will keep this in mind.
Yeah, it's a bit of a stretch goal. 🙃
When I learn a new language, I like to implement the Sieve of Erastothenes (which is a simple algorithm for finding prime numbers), and I had done so with Rust. Two years or so later, I looked back at that code and thought, damn, that looks like a Java dev wrote it.
Then I realized the most idiomatic way of implementing that would be an iterator. This was actually an interesting challenge, because typically Sieve of Erastothenes uses an upper bound, which I didn't want to have.
But yeah, it was also just wild to me, how much different the iterator code looked (and in many ways, how much better it was). It was just really cool to see, how much I had progressed in those two years.
