A funny side effect of building software in Rust: my machine OOMs much more during development.
I'm not entirely sure why. I think Rust makes it easy to allocate data quickly, and sooner or later you write an infinite loop when coding.

In a GC'd language it's just "I have a string" but Rust forces me to find somewhere to put it.
You do get a performance benefit for this work though.
