I know nothing about Rust beyond what it generally is, but how can one be expected to be proficient in a language in only a few week or even months? I’d say you need at least 3-6 months of solid usage in any language before you become “proficient” but it could take years or even a lifetime to truly master one. And of course that really depends on your background and previous experiences with programming languages in general. Is Rust really that hard?
