A New Design for Pretty Printer Implementations in Rust
Summary
The article examines a new Rust-based design for pretty printer implementations, contrasting Wadler-style and Oppen-style approaches and proposing a trait-based Doc design to balance expressive power with Rust’s memory management. It reviews multiple Rust crates (pretty, elegance, pretty-expressive) and reports performance comparisons, including pye’s results showing competitive speeds and memory-management implications.
