Eio 1.0 – Effects-based IO for OCaml 5 / Sep 2023
An update on the OCaml EIO library at the OCaml Workshop 2023. Tom Leonard led this presentation on the release of Eio 1.0, which brings effects-based IO to OCaml 5. This is a big deal for the OCaml ecosystem as it provides a modern approach to concurrent programming using algebraic effects rather than monads or callbacks. The library has been under development for a while and reaching 1.0 is a significant milestone. It's particularly exciting because it takes advantage of OCaml 5's new effect handlers to provide a clean, composable interface for IO operations that feels natural in the language.
