Struct juniper::RootNode

pub struct RootNode<'a, QueryT, MutationT> { /* fields omitted */ }

Root query node of a schema

This brings the mutation and query types together, and provides the predefined metadata fields.

Methods

impl<'a, QueryT, MutationT> RootNode<'a, QueryT, MutationT> where QueryT: GraphQLType,
        MutationT: GraphQLType

fn new(query_obj: QueryT,
       mutation_obj: MutationT)
       -> RootNode<'a, QueryT, MutationT>

Construct a new root node from query and mutation nodes

If the schema should not support mutations, use the new constructor instead.

Trait Implementations

impl<'a, CtxT, QueryT, MutationT> GraphQLType for RootNode<'a, QueryT, MutationT> where QueryT: GraphQLType<Context=CtxT>,
        MutationT: GraphQLType<Context=CtxT>

type Context = CtxT

The expected context type for this GraphQL type

fn name() -> Option<&'static str>

The name of the GraphQL type to expose.

fn meta<'r>(registry: &mut Registry<'r>) -> MetaType<'r>

The meta type representing this GraphQL type.

fn resolve_field(&self,
                 field: &str,
                 args: &Arguments,
                 executor: &Executor<CtxT>)
                 -> ExecutionResult

fn resolve_into_type(&self,
                     type_name: &str,
                     selection_set: Option<&[Selection]>,
                     executor: &Executor<Self::Context>)
                     -> ExecutionResult

Resolve this interface or union into a concrete type

fn concrete_type_name(&self, context: &Self::Context) -> String

Return the concrete type name for this instance/union.

fn resolve(&self,
           selection_set: Option<&[Selection]>,
           executor: &Executor<Self::Context>)
           -> Value
