I've been struggling for the past few days with setting up mock dependencies in unit tests for a #rust project. This is first time I'm using mocks in Rust, and it feels like pushing a boulder up a hill. The idea is to swap out types of dependencies with your own implementations, so that you can measure how your own code-under-test behaves while interacting with a dependency. The borrow-checker cop, and design choices that authors of a library can make, conspire against me.
