I find Rust's complexity freeing, in that there are often at least a few ways to express what I want, and I can choose the one I feel best fits the use-case and my desired ergonomics. (I also like that there are often ways to express exactly a very precise want, owing well to the Rust principle of "zero-cost abstractions.") However of course, that very same complexity can make it unclear which approach may best serve a given objective, and lead to false starts, wacky implementations, or even giving up entirely.
