Description
Input types and values.
This module is intended to be imported qualified, to avoid name clashes
with Out.

Documentation
Field argument definition.
data InputField Source #
Single field of an InputObjectType.
data InputObjectType Source #
Input object type definition.
An input object defines a structured collection of fields which may be supplied to a field argument.

These types may be used as input types for arguments and directives.
GraphQL distinguishes between "wrapping" and "named" types. Each wrapping type can wrap other wrapping or named types. Wrapping types are lists and Non-Null types (named types are nullable by default).
isNonNullType :: Type -> Bool Source #
Checks whether the given input type is a non-null type.
pattern EnumBaseType :: EnumType -> Type Source #
Matches either NamedEnumType or NonNullEnumType.
pattern ListBaseType :: Type -> Type Source #
Matches either ListType or NonNullListType.
pattern InputObjectBaseType :: InputObjectType -> Type Source #
Matches either NamedInputObjectType or NonNullInputObjectType.
pattern ScalarBaseType :: ScalarType -> Type Source #
Matches either NamedScalarType or NonNullScalarType.
