You're saying it's "a common term", but I'd literally never heard it before a Rust library with this exact name appeared. Isn't this by any chance circular reasoning? That it became "a common term" because of this library? In that case you couldn't justify the name of the library by saying that it was "a common term" at that time.
My $0.02 - I've heard of it and I've never worked in Rust, though calling it "a common term" seems like a bit of a stretch - I was over 5 years into my career before I encountered it. It's much less common than analogous terms like modem ("modulator-demodulator").
