effects

What problem does it solve?

This Skill helps OCaml developers design robust control-flow patterns using algebraic effects, separating suspension from errors to create clean, testable code paths.

Core Features & Use Cases

• Design APIs with effect-based schedulers: structure interactions between components using effects rather than exceptions.
• Compare effects vs exceptions: evaluate when to suspend versus raise errors in streaming code.
• Integrate libraries with Eio or affect: enabling effect-aware I/O and concurrency models.
• Handle suspension vs error cases in streaming code: clear flow control in data pipelines.

Quick Start

Start with a minimal OCaml project configured for OCaml 5. Then implement a simple effect like Block and a handler, and run a small function that uses the effect.
