Struct SharedServerProtocol 

pub struct SharedServerProtocol(/* private fields */);

Shared, erased server protocol selected by routing.

Wraps one of the routing kinds — metadata_routed or body_routed — or a routing-less serde handle (serde_only). The kind decides which SharedProtocolRouter variant is constructed and whether the protocol can answer the event-stream question; everything after routing works through the ServerProtocol this dereferences to. The kind stays private: the constructors’ trait bounds are what guarantee each variant builds the matching router, so nothing else may assemble one.

Implementations

impl SharedServerProtocol

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

Borrows the protocol selected for this request from its extensions.

Reads the protocol through SelectedOperation::get_from_request. Returns None if no selection is stored, including before schema routing runs.

pub fn metadata_routed(protocol: impl MetadataRoutedProtocol) -> Self

Wraps a protocol that selects operations from request metadata alone.

pub fn body_routed(protocol: impl BodyRoutedProtocol) -> Self

Wraps a protocol that reads the request body to select operations.

A body-routed protocol cannot express event-stream framing — the subtrait has no such method — so this handle always answers None from Self::event_stream_framing.

pub fn serde_only(protocol: impl ServerProtocol) -> Self

Wraps a protocol for serialization only, without routing or event-stream support.

For handles that never route: middleware serializing through a hand-built protocol, and tests. Registration requires one of the routed constructors, so this handle is never asked to build a router.

pub fn event_stream_framing(&self) -> Option<EventStreamFraming<'_>>

Event-frame support, when this protocol supports event streams.

Only a metadata-routed protocol can answer: the BodyRoutedProtocol subtrait has no framing method (an event-stream body must not be collected), and a serde-only handle never routes.
