Before you start

You need Rust and Cargo. Familiarity with structs, Result and basic async Rust is enough. The repository is tested with Rust 1.98.1. SQLite is bundled; the default tutorial path needs no database service or API credentials. For the complete runnable examples, start from the repository revision matching these docs:
These tutorials target Rydantic 0.7.0 stable and RydanticAI 0.6.0. A pull request preview can include examples that reach the default branch when merged. Use that pull request’s source checkout when following a preview.
The first-model and typed-agent tutorials also include standalone Cargo.toml files. Copy their complete source into src/main.rs to run outside the workspace.
