Steve Klabnik recently wrote about whether out parameters are idiomatic in Rust. The post ends by showing a snippet of code: a generic function, with a non-generic function inside of it which contains the actual implementation. Steve says this pattern may warrant its own post, so here is that post, where I’ll explain why this inner function is useful, discuss the trade-offs of doing it, and describe why this pattern will hopefully not be necessary in the future.

In this post, I’ll explain what each of these lints does, and why it might be useful.
