# Copyright 2019-present, GraphQL Foundation

# Mini-language for AST definition.
# All AST nodes extend AstNode.
# All AST nodes are visitible.
# All AST fields have a getter and a setter and are a constructor argument.
# We have concrete types (code T) and unions (code U).
# S for singular field, P for plural, ? for nullable.
# O for option in a union.
# Scalar type ontology: string, boolean

# Definitions other than OperationDefinition and FragmentDefinition
# are experimental additions for schema parsing. (We don't support
# nested unions in the AST mini-language, so I've flattened and elided
# TypeSystemDefinition and TypeDefinition.)
