Declarative programming in Rust
summary
Rust claims yield zero-cost abstractions and shows concrete wins: replacing loops with iterators reduces work and beats the naive loop in examples (take(5) stops early), derive-based code generation removes JSON and CLI boilerplate via derive macros, and crates named clap and struct up (plus get out) generate help/version/arg parsing so less manual parsing is written. A web-example wires a FromRequest-style extractor to parse JSON into types. Beware that high abstraction can feel like magic and needs measurement and tool support like cargo expand or Clippy.
