Struct GraphqlTranslator 

pub struct GraphqlTranslator { /* private fields */ }

The REST-to-GraphQL / GraphQL-to-REST translator.

Implementations

impl GraphqlTranslator

pub fn rest_to_graphql( cfg: &GraphqlTranslation, ) -> Result<Self, TranslationError>

Build a REST-to-GraphQL translator from a route’s GraphQL translation config.

pub fn graphql_to_rest() -> Self

Build a GraphQL-to-REST translator. The reverse direction only unwraps the GraphQL data envelope on the response path, so no query template is required.

pub fn direction(&self) -> GraphqlDirection

The configured direction.

Trait Implementations

impl Clone for GraphqlTranslator

fn clone(&self) -> GraphqlTranslator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GraphqlTranslator

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

Formats the value using the given formatter.

impl ProtocolTranslator for GraphqlTranslator

fn translate_request( &self, req: &Request<TranslationBody>, ) -> Result<TranslatedRequest, TranslationError>

Convert the inbound request to the upstream’s wire format. The translator reads req’s body (via TranslationBody::as_bytes) and returns the converted method, path, headers, and body to send upstream.

fn translate_response( &self, resp: &Response<TranslationBody>, ) -> Result<TranslatedResponse, TranslationError>

Convert the upstream response to the client’s wire format. The translator reads resp’s body and returns the converted status, headers, and body to send the client.

fn content_type_in(&self) -> &str

The media type the CLIENT sends and expects back (e.g. application/json for a REST client, text/xml for a SOAP client).

fn content_type_out(&self) -> &str

The media type the UPSTREAM expects and sends back (e.g. application/graphql for a GraphQL upstream, application/xml for a SOAP upstream, application/grpc for a gRPC upstream).
