pub struct GraphQLWebSocket<Sink, Stream, Query, Mutation, Subscription, OnConnInit> { /* private fields */ }

A Websocket connection for GraphQL subscription.

Implementations

impl<S, Query, Mutation, Subscription> GraphQLWebSocket<SplitSink<S, Message>, SplitStream<S>, Query, Mutation, Subscription, fn(_: Value) -> Ready<Result<Data>>>where
    S: Stream<Item = Result<Message, Error>> + Sink<Message>,
    Query: ObjectType + 'static,
    Mutation: ObjectType + 'static,
    Subscription: SubscriptionType + 'static,

pub fn new(
    stream: S,
    schema: Schema<Query, Mutation, Subscription>,
    protocol: GraphQLProtocol
) -> Self

Create a GraphQLWebSocket object.

impl<Sink, Stream, Query, Mutation, Subscription> GraphQLWebSocket<Sink, Stream, Query, Mutation, Subscription, fn(_: Value) -> Ready<Result<Data>>>where
    Sink: Sink<Message>,
    Stream: Stream<Item = Result<Message, Error>>,
    Query: ObjectType + 'static,
    Mutation: ObjectType + 'static,
    Subscription: SubscriptionType + 'static,

pub fn new_with_pair(
    sink: Sink,
    stream: Stream,
    schema: Schema<Query, Mutation, Subscription>,
    protocol: GraphQLProtocol
) -> Self

Create a GraphQLWebSocket object with sink and stream objects.

impl<Sink, Stream, Query, Mutation, Subscription, OnConnInit, OnConnInitFut> GraphQLWebSocket<Sink, Stream, Query, Mutation, Subscription, OnConnInit>where
    Sink: Sink<Message>,
    Stream: Stream<Item = Result<Message, Error>>,
    Query: ObjectType + 'static,
    Mutation: ObjectType + 'static,
    Subscription: SubscriptionType + 'static,
    OnConnInit: FnOnce(Value) -> OnConnInitFut + Send + 'static,
    OnConnInitFut: Future<Output = Result<Data>> + Send + 'static,

pub fn with_data(self, data: Data) -> Self

Specify the initial subscription context data, usually you can get something from the incoming request to create it.

pub fn on_connection_init<OnConnInit2, Fut>(
    self,
    callback: OnConnInit2
) -> GraphQLWebSocket<Sink, Stream, Query, Mutation, Subscription, OnConnInit2>where
    OnConnInit2: FnOnce(Value) -> Fut + Send + 'static,
    Fut: Future<Output = Result<Data>> + Send + 'static,

Specify a callback function to be called when the connection is initialized.

You can get something from the payload of GQL_CONNECTION_INIT message to create Data. The data returned by this callback function will be merged with the data specified by [with_data].

pub async fn serve(self)

Processing subscription requests.
