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

[−] Expand description

GraphQL schema.

Cloning a schema is cheap, so it can be easily shared.

Implementations

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 fn sdl() -> String[−]

Returns SDL(Schema Definition Language) of this schema.

pub async fn execute<'_>(&'_ self, request: impl Into<Request>) -> Response[−]

Execute an GraphQL query.

pub async fn execute_batch<'_>(
    &'_ self,
    batch_request: BatchRequest
) -> BatchResponse[−]

Execute an GraphQL batch query.

pub fn execute_stream(
    &self,
    request: impl Into<Request>
) -> impl Stream<Item = Response> + Send[−]

Execute an GraphQL subscription.
