StructSchema

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

GraphQL schema.

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

Implementations§

Source§

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

Source

pub fnbuild( 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 useEmptyMutation.If there is no subscription, you can useEmptySubscription.

Source

pub fnbuild_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 conflictdetection.

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

Source

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

Create a schema

Source

pub fnsdl(&self) ->String

Returns SDL(Schema Definition Language) of this schema.

Source

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

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

Source

pub fnnames(&self) ->Vec<String>

Get all names in this schema

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

Source

pub async fnexecute(&self, request: implInto<Request>) ->Response

Execute a GraphQL query.

Source

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

Execute a GraphQL batch query.

Source

pub fnexecute_stream_with_session_data( &self, request: implInto<Request>, session_data:Arc<Data>,) -> implStream<Item =Response> +Send +Unpin + 'static

Execute a GraphQL subscription with session data.

Source

pub fnexecute_stream( &self, request: implInto<Request>,) -> implStream<Item =Response> +Send +Unpin

Execute a GraphQL subscription.
