Struct SelectedOperation 

pub struct SelectedOperation { /* private fields */ }

A read-only view of the protocol and operation selected by routing, with the operation’s request-body limits.

The protocol is erased: everything after routing works through dyn ServerProtocol.

The operation schema is stored for consumers that are not generic over the operation: middleware and FromParts extractors use get_from_request or get_from_extensions to learn which operation was selected — for logging, auth, or metrics — without naming an Op type. See the middleware example on ServerProtocol.

Routing stores this view in a private extension carrier. Inserting or removing SelectedOperation directly in request extensions does not change the routed selection. Middleware must preserve request extensions: clearing or replacing all extensions removes the carrier, causing the upgrade or missing-handler fallback to return an empty 500 without polling the body or invoking the handler. Routing may already have collected the body before middleware runs.

Implementations

impl SelectedOperation

pub fn get_from_request<B>(request: &Request<B>) -> Option<&Self>

Borrows the protocol and operation selected for this request from its extensions.

Returns None if no selection is stored, including before schema routing runs.

pub fn get_from_extensions(extensions: &Extensions) -> Option<&Self>

Borrows the routed selection from request extensions, including in a FromParts extractor.

Returns None before routing or if middleware discarded the request extensions.

pub fn protocol(&self) -> &SharedServerProtocol

The selected protocol.

pub fn operation(&self) -> &'static OperationSchema<'static>

The routed operation’s schema, for code that cannot name the operation type.

pub fn request_body_config(&self) -> RequestBodyCollectionConfig

The routed operation’s request-body collection limits, resolved when the router was built.

Carrying them here keeps the per-operation upgrade services free of per-operation state.
