Rust Docs

Rust APIs, examples, recipes, integrations, and generated rustdoc for building graph-driven reactive systems with the graphrefly crate.

Start here

• Quick Start — build and observe a tiny graph in Rust.
• API Reference — generated rustdoc for the public crate surface.
• Examples — package-local Rust entry points.
• Recipes — composition and runtime-boundary notes.
• Integrations — native host, IO, and wire bridge surfaces.
• Release — crates.io, docs.rs, and Pages publishing notes.
