I think Rust is in a category of it's own, mostly due to circumstances rather than anything: The ecosystem has grown immensely over the past several years and you can find a crate to solve most of your needs. But here is where thing become tricky: more often than not the documentation provided is extremely vague to put it mildly and the examples are a hello world at best. With this in mind, in order to truly use it you have little to no choice but to dig deep into the implementation and at some point reach the standard library.
