Hi all, I'm learning Rust and for a project I would need a percolator library, so I thought well, why not write my own. The result is https://crates.io/crates/mokaccino and I would love to get some improvement suggestions from rustier rustaceans, as I'm sure this code is not the most idiomatic.

In particular, for some reason I can't put my finger on, I'm not 100% happy with the heavy use of Rc<str> but I'm still wondering what's the best way to avoid lot of strings allocations, as this is software heavily relying on strings.
