Add type safe state extractor (#1155)
* begin threading the state through * Pass state to extractors * make state extractor work * make sure nesting with different states work * impl Service for MethodRouter<()> * Fix some of axum-macro's tests * Implement more traits for `State` * Update examples to use `State` * consistent naming of request body param * swap type params * Default the state param to () * fix docs references * Docs and handler state refactoring * docs clean ups * more consistent naming * when does MethodRouter implement Service? * add missing docs * use `Router`'s default state type param * changelog * don't use default type param for FromRequest and RequestParts probably safer for library authors so you don't accidentally forget * fix examples * minor docs tweaks * clarify how to convert handlers into services * group methods in one impl block * make sure merged `MethodRouter`s can access state * fix docs link * test merge with same state type * Document how to access state from middleware * Port cookie extractors to use state to extract keys (#1250) * Updates ECOSYSTEM with a new sample project (#1252) * Avoid unhelpful compiler suggestion (#1251) * fix docs typo * document how library authors should access state * Add `RequestParts::with_state` * fix example * apply suggestions from review * add relevant changes to axum-extra and axum-core changelogs * Add `route_service_with_tsr` * fix trybuild expectations * make sure `SpaRouter` works with routers that have state * Change order of type params on FromRequest and RequestParts * reverse order of `RequestParts::with_state` args to match type params * Add `FromRef` trait (#1268) * Add `FromRef` trait * Remove unnecessary type params * format * fix docs link * format examples * Avoid unnecessary `MethodRouter` * apply suggestions from review Co-authored-by: Dani Pardo <[email protected]> Co-authored-by: Jonas Platte <[email protected]>
