In response to the call for blogs about the vision for Rust for 2020, I’m going to write about GUI. I believe the time is right for a native GUI toolkit written in Rust, and that such a thing would fill a very important niche. There is a demand for performance (which, to me, includes startup time, RAM footprint, and binary size), and Rust is in the best position to deliver on that.
