Struct RpcV2CborProtocol 

pub struct RpcV2CborProtocol { /* private fields */ }

RPC v2 CBOR protocol (smithy.protocols#rpcv2Cbor).

Implementations

impl RpcV2CborProtocol

pub fn new() -> Self

Creates a new RPC v2 CBOR protocol instance.

Trait Implementations

impl ClientProtocolInner for RpcV2CborProtocol

fn event_stream_media_type(&self) -> Option<&str>

This protocol labels structured event-stream payloads application/cbor.

Must stay in agreement with the code generator’s eventStreamMessageContentType for this protocol (RpcV2Cbor.kt:115), which supplies the fallback when a protocol declares no media type.

fn parse_event_stream_error_metadata( &self, payload: &[u8], ) -> Result<ErrorMetadataBuilder, SerdeError>

Parses the same CBOR error envelope as [ClientProtocolInner::parse_error_metadata], from an event-stream frame’s payload rather than an HTTP response body. An event-stream frame has no HTTP headers, so an empty header map is passed.

type Request = Request

The protocol’s request message type (e.g., http::Request).

type Response = Response

The protocol’s response message type (e.g., http::Response).

fn protocol_id(&self) -> &ShapeId<'static>

Returns the Smithy shape ID of this protocol.

fn serialize_request( &self, input: &dyn SerializableStruct, input_schema: &Schema<'_>, endpoint: &str, cfg: &ConfigBag, ) -> Result<Request, SerdeError>

Serializes an operation input into a request message.

fn deserialize_response<'a>( &self, response: &'a Response, output_schema: &Schema<'_>, cfg: &'a ConfigBag, ) -> Result<Box<dyn ShapeDeserializer + 'a>, SerdeError>

Deserializes a response message, returning a boxed [ShapeDeserializer] that supplies every member of output_schema this protocol carries in the response.

fn payload_codec(&self) -> Option<&dyn DynCodec>

Returns the codec used for payload (de)serialization, if any.

fn update_endpoint( &self, request: &mut Request, endpoint: &Endpoint, cfg: &ConfigBag, ) -> Result<(), SerdeError>

Updates a previously serialized request with a resolved endpoint.

fn parse_error_metadata( &self, response: &Response, _cfg: &ConfigBag, ) -> Result<ErrorMetadataBuilder, SerdeError>

Extracts canonical error metadata (code, message, request id) from a response’s wire envelope.

fn deserialize_error_response<'a>( &self, response: &'a Self::Response, cfg: &'a ConfigBag, ) -> Result<Box<dyn ShapeDeserializer + 'a>, SerdeError>

Returns a [ShapeDeserializer] positioned at the body of an error response — inside the protocol’s error envelope, where applicable.

impl Debug for RpcV2CborProtocol

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RpcV2CborProtocol

fn default() -> Self

Returns the “default value” for a type.
