The Eternal Sunshine of the Spotless Programming Language
summary
Argues that Rust’s trait system is the practical win: traits as glue let code express relationships, hook into language features (Result + ? operator, Future for async, custom allocator) and reduce a 20-line image-grayscale handler using the image crate, web framework and a KV store to a four-line call that compiles and bubbles errors. Cites surprising legacy costs (C++ spec ~10,000 pages, Google case of 2,000 files expanding to 8 GB of includes) to justify a clean, zero-cost-abstraction approach. image response becomes a noun, not string plumbing.
