It's a lot of hidden things, you're not completely useless of course, but it's not like you write "production quality" code and have the ability to wo…
(Also Haskell to Rust is pretty straightforward, the typesystem knowledge you learn in Haskell usually means the harder parts of learning rust are made easy. Having done that transition, 1 month is reasonable to be productive in Rust)
