Struct juniper::RootNode
[−]
[src]
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
[src]
fn new(query_obj: QueryT,
mutation_obj: MutationT)
-> RootNode<'a, QueryT, MutationT>
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.
