Is Eio ready for production use?

Eio is the recommended IO library for OCaml 5, leveraging modern kernel features like io_uring on Linux and Grand Central Dispatch on macOS for high-performance networking.

What is capability-based design in Eio?

It is a security pattern where functions must be explicitly passed resources (like a network or filesystem capability) instead of using global state, making code more testable and secure.

How does Eio differ from Lwt or Async?

Eio uses OCaml 5 effects for direct-style code, meaning you write concurrent code like sequential code without monads, resulting in better performance and clearer backtraces.

Can I use Eio with existing Lwt libraries?

Yes, the Lwt_eio library allows you to run Lwt and Eio code together, providing a gradual migration path for existing OCaml applications.

How does Eio handle resource cleanup?

Eio uses 'Switches' to implement structured concurrency, ensuring that resources like file descriptors and fibers are automatically closed or cancelled when a scope finishes.

API 개발

Implements high-performance, direct-style concurrent IO for OCaml 5 applications using the Eio effects-based library.

소개

OCaml Eio Concurrency provides Claude with specialized knowledge for building modern OCaml 5 applications using structured concurrency and effects-based IO. It enables the creation of efficient, direct-style code that avoids the complexity of monads (Lwt/Async) while offering superior performance, platform-optimized backends like io_uring, and better backtraces. This skill covers core Eio concepts including capability-based design, resource management with switches, fiber manipulation, network operations via cohttp-eio, and robust testing patterns using Eio_mock, ensuring your OCaml code is both performant and maintainable.
