It really depends on the problems you work on. For my first program (task scheduling, regexes, redis, rest), everything was simple and obvious, it was made in about 3 days. My second program was dealing with several kinds of graphs, optimal sub string addressing, and then I hit the painful points and it took me several weeks of this side project to get my head around the complex concepts of Rust, and several months to really feel at ease. There's a subset of problems for which Rust is "easy" and it's probably possible, with some guidance and occasional help, to organize one's work around those.
