Really good video by Conor Hoekstra on the differences between C++ Concepts vs. Haskell Typeclasses vs. Rust Traits vs. Swift Protocols.

It is a good intro overview to the subject. Unfortunately the video has far too much filler, so you need to skip a bit e.g. start at 22:30 when the video gets into examples.
