Rust's stdlib is similarly bare-bones. Rust/Cargo has the same mindset of many small packages as JS/npm. The difference is that in JS abstraction and indirection has a run-time cost, so doing things via packages adds overhead. In Rust, you can have zero-cost abstractions that optimize away. The runtime and code-size cost is often the same whether you call code from a generic 3rd party crate or write it yourself inline in your function.
