Struct juniper::RootNode

pub struct RootNode<'a, QueryT: GraphQLType<S>, MutationT: GraphQLType<S>, S = DefaultScalarValue>where
    S: ScalarValue,
    for<'b> &'b S: ScalarRefValue<'b>,{ /* private fields */ }

Root query node of a schema

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

Implementations

impl<'a, QueryT, MutationT, S> RootNode<'a, QueryT, MutationT, S>where
    S: ScalarValue + 'a,
    QueryT: GraphQLType<S, TypeInfo = ()>,
    MutationT: GraphQLType<S, TypeInfo = ()>,
    for<'b> &'b S: ScalarRefValue<'b>,

pub fn new(query_obj: QueryT, mutation_obj: MutationT) -> Selfwhere
    for<'b> &'b S: ScalarRefValue<'b>,

Construct a new root node from query and mutation nodes

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

impl<'a, S, QueryT, MutationT> RootNode<'a, QueryT, MutationT, S>where
    QueryT: GraphQLType<S>,
    MutationT: GraphQLType<S>,
    S: ScalarValue + 'a,
    for<'b> &'b S: ScalarRefValue<'b>,

pub fn new_with_info(
    query_obj: QueryT,
    mutation_obj: MutationT,
    query_info: QueryT::TypeInfo,
    mutation_info: MutationT::TypeInfo
) -> Selfwhere
    for<'b> &'b S: ScalarRefValue<'b>,

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