GraphQLSchema class

/ A GraphQL Schema definition without field resolution capacities.

A schemahttps://spec.graphql.org/draft/#sec-Schema) represents a GraphQL service’s collective type system capabilities.

A schema is defined in terms of the types and directives it supports as well as the root operation types for each kind of operation (OperationTypeDefinition): query, mutation, and subscription; this determines the place in the type system where those operations begin.
