Been using ripgrep for a while now, I love it. One other Rust tool people might find useful is fd (<a href="https://github.com/sharkdp/fd" rel="nofollow">https://github.com/sharkdp/fd</a>) which is similar to find.
I just installed Fedora 27 in a VM out of curiosity. As far as I can tell from a quick glance, it looks like these Rust executables (ternimal, tokei) statically link their dependent Rust crates (including the Rust standard library), which is the typical approach to building Rust programs. I do wonder if someday we'll see distributions arranging a common dependency realm (as much as possible) among their Rust programs so that shared libraries can be used to reduce the total memory and storage footprint.
How about replacing the core utilities?<p><a href="https://github.com/uutils/coreutils" rel="nofollow">https://github.com/uutils/coreutils</a>
