pub struct Schema<Query, Mutation, Subscription>(_);

GraphQL schema

Methods

impl<Query, Mutation, Subscription> Schema<Query, Mutation, Subscription> where
    Query: ObjectType + Send + Sync + 'static,
    Mutation: ObjectType + Send + Sync + 'static,
    Subscription: SubscriptionType + Send + Sync + 'static, 

pub fn build(
    query: Query,
    mutation: Mutation,
    subscription: Subscription
) -> SchemaBuilder<Query, Mutation, Subscription>

Create a schema builder

The root object for the query and Mutation needs to be specified. If there is no mutation, you can use EmptyMutation. If there is no subscription, you can use EmptySubscription.

pub fn new(
    query: Query,
    mutation: Mutation,
    subscription: Subscription
) -> Schema<Query, Mutation, Subscription>

Create a schema

pub async fn execute<'_, '_>(
    &'_ self,
    query_source: &'_ str
) -> Result<QueryResponse>

Execute query without create the QueryBuilder.

pub async fn create_subscription_stream<'_, '_, '_>(
    &'_ self,
    source: &'_ str,
    operation_name: Option<&'_ str>,
    variables: Variables,
    ctx_data: Option<Arc<Data>>
) -> Result<impl Stream<Item = Value> + Send>

Create subscription stream, typically called inside the SubscriptionTransport::handle_request method

pub fn subscription_connection<T: SubscriptionTransport>(
    &self,
    transport: T
) -> (Sender<Bytes>, SubscriptionStream<Query, Mutation, Subscription, T>)

Create subscription connection, returns Sink and Stream.
