A "ton of crates" is IMO the best way to write large Rust programs. Each crate in Rust is a compilation unit, the equivalent of one `.c` file in C. If they don't depend on one another, each crate can be compiled in parallel. It makes building the whole project faster, often significantly so. As with anything one can take it too far, but as long as each crate makes sense as an independent unit it's good.

Gotta add a +1 for this. I wanted to do some ignore files etc for a project.

I thought "well I kinda want to do what rg does". Had a little glance and it was already nicely extracted into a separate crate that was a dream to use.

Thanks @BurntSushi!

looks abandoned. last commit was 2 years ago.

Note that this is the author of ripgrep replying to a third party commenter asking whether rg isn’t already lightweight, and comparing the two under various possible definitions of “lightweight”.
