Module extract 

Typed request extractors (Path, Query, Json, …) for IntoHandler.

Existing async fn(req: Request) handlers keep working. Extractor handlers use separate marker impls so they do not conflict with Fn(Request).

Structs

Extension

Per-request extension (req.set / req.get).

Form

application/x-www-form-urlencoded (or multipart text fields) into T.

Json

JSON body deserialized into T.

Path

Path parameters deserialized into T (e.g. struct Id { id: String } for /:id).

Query

Query string deserialized into T.

State

Shared app state registered via app.state(T).

Traits

FromRequest

Extract a value from the request (may read the body).

FromRequestParts

Extract a value from request parts (no body).

Type Aliases

ExtractFuture

Boxed future tied to the request borrow (body extractors).
