Struct async_graphql::Schema

pub struct Schema<Query, Mutation, Subscription>(/* private fields */);

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 + 'static, Mutation: ObjectType + 'static, Subscription: SubscriptionType + '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 build_with_ignore_name_conflicts<I, T>( query: Query, mutation: Mutation, subscription: Subscription, ignore_name_conflicts: I ) -> SchemaBuilder<Query, Mutation, Subscription>where I: IntoIterator<Item = T>, T: Into<String>,

Create a schema builder and specifies a list to ignore type conflict detection.

NOTE: It is not recommended to use it unless you know what it does.

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

Create a schema

pub fn sdl(&self) -> String

Returns SDL(Schema Definition Language) of this schema.

pub fn sdl_with_options(&self, options: SDLExportOptions) -> String

Returns SDL(Schema Definition Language) of this schema with options.

pub fn names(&self) -> Vec<String>

Get all names in this schema

Maybe you want to serialize a custom binary protocol. In order to minimize message size, a dictionary is usually used to compress type names, field names, directive names, and parameter names. This function gets all the names, so you can create this dictionary.

pub async fn execute(&self, request: impl Into<Request>) -> Response

Execute a GraphQL query.

pub async fn execute_batch(&self, batch_request: BatchRequest) -> BatchResponse

Execute a GraphQL batch query.

pub fn execute_stream_with_session_data( &self, request: impl Into<Request>, session_data: Arc<Data> ) -> impl Stream<Item = Response> + Send + Unpin

Execute a GraphQL subscription with session data.

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

Execute a GraphQL subscription.

Trait Implementations

impl<Query, Mutation, Subscription> Clone for Schema<Query, Mutation, Subscription>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Query, Mutation, Subscription> Default for Schema<Query, Mutation, Subscription>where Query: Default + ObjectType + 'static, Mutation: Default + ObjectType + 'static, Subscription: Default + SubscriptionType + 'static,

fn default() -> Self

Returns the “default value” for a type.
