In addition to the high likelihood that they are asking for an advanced junior dev "Picking between an Arc<T>, a Box<T>, and an &T is second nature to you." (Not that advanced of a skill), even if they have a closed source webapp, they are still predominantly open source (that position is for that part), they don't have much money. For that it's not great, but not horrible either.

Abstract Impl: code generic trait implementations
cross-posted from: https://feddit.org/post/7326044
Inspired by Contex-Generic Programming, I made this macro, that allows you to write those generic implementations easily. This is kinda CGP, but simple and with better errors.
Ever repeat yourself implementing traits? Or wanted to easily swap out parts of your code, with (almost) no need to refactor? That is what this is for.
