Personally I think the docs are a bit lacking as well. For example, the section in the manual on enums doesn't really clarify what the tuple after the symbol represents. It was only later I realized that Nim enums were similar to C enums from another (probably non-official) source of docs.
Although Rust arguably has a steeper learning curve, I feel the docs are more comprehensive. They provide examples, but also explain the context so that it's easier to understand even without a background in computer science. The Rust compiler also provides friendly suggestions and shows clearly where the error is. That being said, I understand of course that the Rust community has much more manpower. But all in all, the Rust ecosystem feels like a lot of effort was put in to make it a welcoming experience for people of various backgrounds and skill levels.
