This is an overview/tutorial of the Rust programming language for progrmamers coming from 'higher' level languages.
The Rust Programming Language - aka 'The Book' is a great resource and should certainly be used in conjuction with the content if you are new to Rust programming.
Rust code and libraries are also easily 'self-documented', and one of the best examples is the std crate. (a crate being the equivilant of an npm or nuget package). std For core concepts (e.g. references, types, etc.), the api documentation often provides conceptual context that is very helpful.
