The post discusses the advancements in Rust’s incremental compiler architecture, with comparisons to technologies in other languages, such as Scala.js, and references to various tools and concepts like rust-analyzer, LLVM, and alternatives like Cranelift. User comments express both enthusiasm about Rust’s developments and frustrations concerning its compile speed relative to other languages such as OCaml. Points are also raised about the plateauing performance improvements noted in benchmarks and inquiries on how efforts towards incremental compilation are prioritized. Additionally, the conversation highlights the broader applicability of incremental techniques in build systems and machine learning frameworks.
