Struct AwsQueryProtocol 

pub struct AwsQueryProtocol { /* private fields */ }

Implementations

impl AwsQueryProtocol

pub fn new() -> Self

Creates an awsQuery protocol instance.

The Version= form parameter defaults to the Smithy service shape’s version from the config bag; use Self::with_service_version to override it.

pub fn with_service_version(self, version: impl Into<String>) -> Self

Overrides the Version= form parameter.

By default it comes from the [ServiceVersion] config-bag entry that generated clients store regardless of which protocol they were generated for. That default exists because a customer selecting awsQuery through Config::builder().protocol(..) has no way to know the model’s version, and awsQuery requires the parameter on every request.

Trait Implementations

impl ClientProtocolInner for AwsQueryProtocol

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

Serializes an awsQuery request.

_endpoint is deliberately ignored: awsQuery fixes the request path at / (its StaticHttpBindingResolver uses @http(method: "POST", uri: "/")), so the route is a function of the protocol rather than of the operation, and a path computed by codegen for a different protocol must not leak through when this protocol is selected at runtime via Config::builder().protocol(..). apply_http_endpoint merges the scheme and authority afterwards.

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 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 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: &Self::Response, cfg: &ConfigBag, ) -> Result<Builder, 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.

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

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

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

The media type used to label a structured event-stream payload, if this protocol supports event streams — for example application/cbor or application/json.

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

Extracts canonical error metadata from the payload of an event-stream exception frame.

impl Debug for AwsQueryProtocol

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

Formats the value using the given formatter.

impl Default for AwsQueryProtocol

fn default() -> Self

Returns the “default value” for a type.
