Struct juniper::RootNode

pub struct RootNode<'a, QueryT: GraphQLType, MutationT: GraphQLType> { /* 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<TypeInfo = ()>,
    MutationT: GraphQLType<TypeInfo = ()>, 

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.

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

fn new_with_info(
    query_obj: QueryT,
    mutation_obj: MutationT,
    query_info: QueryT::TypeInfo,
    mutation_info: MutationT::TypeInfo
) -> RootNode<'a, QueryT, MutationT>

Construct a new root node from query and mutation nodes, while also providing type info objects for the query and mutation types.

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

type TypeInfo = QueryT::TypeInfo

Type that may carry additional schema information

fn name(info: &QueryT::TypeInfo) -> Option<&str>

The name of the GraphQL type to expose.

fn meta<'r>(
    info: &QueryT::TypeInfo,
    registry: &mut Registry<'r>
) -> MetaType<'r>

The meta type representing this GraphQL type.

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

Resolve the value of a single field on this type.

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

Resolve the provided selection set against the current object.
