Extension of GraphQLValue trait with asynchronous queries/mutations resolvers.

Convenience macros related to asynchronous queries/mutations expand into an implementation of this trait and GraphQLValue for the given type.

Provided Methods

fn resolve_field_async<'a>( &'a self, _info: &'a Self::TypeInfo, _field_name: &'a str, _arguments: &'a Arguments<'_, S>, _executor: &'a Executor<'_, '_, Self::Context, S>, ) -> BoxFuture<'a, ExecutionResult<S>>

Resolves the value of a single field on this GraphQLValueAsync.

The arguments object contains all the specified arguments, with default values being substituted for the ones not provided by the query.

The executor can be used to drive selections into sub-objects.

Panics

The default implementation panics.

fn resolve_into_type_async<'a>( &'a self, info: &'a Self::TypeInfo, type_name: &str, selection_set: Option<&'a [Selection<'a, S>]>, executor: &'a Executor<'a, 'a, Self::Context, S>, ) -> BoxFuture<'a, ExecutionResult<S>>

Resolves this GraphQLValueAsync (being an interface or an union) into a concrete downstream object type.

Tries to resolve this GraphQLValueAsync into the provided type_name. If the type matches, then passes the instance along to Executor::resolve.

Panics

The default implementation panics.

fn resolve_async<'a>( &'a self, info: &'a Self::TypeInfo, selection_set: Option<&'a [Selection<'_, S>]>, executor: &'a Executor<'_, '_, Self::Context, S>, ) -> BoxFuture<'a, ExecutionResult<S>>

Resolves the provided selection_set against this GraphQLValueAsync.

For non-object types, the selection_set will be None and the value should simply be returned.

For objects, all fields in the selection_set should be resolved. The default implementation uses GraphQLValueAsync::resolve_field_async to resolve all fields, including those through a fragment expansion.

Since the GraphQL spec specifies that errors during field processing should result in a null-value, this might return Ok(Null) in case of a failure. Errors are recorded internally.

Panics

The default implementation panics, if selection_set is None.
