(I'm learning Rust by implementing a simple Lisp interpreter in it)
I think TFA is a great resource in terms of presenting syntax and idioms. My biggest problem with learning Rust though has been understanding how to do things when the borrow checker prohibits the solution that would be 'obvious' in C#, C++, etc. I started to make progress when I bought the O'Reilly Programming in Rust book, and then thoroughly read and re-read the chapter on memory management.
