Input types and values.

This module is intended to be imported qualified, to avoid name clashes with Out.

Documentation

data Argument

Field argument definition.

Constructors

Argument (Maybe Text) Type (Maybe Value)

type Arguments = HashMap Name Argument

Field argument definitions.

data InputField

Single field of an InputObjectType.

Constructors

InputField (Maybe Text) Type (Maybe Value)

data InputObjectType

Input object type definition.

An input object defines a structured collection of fields which may be supplied to a field argument.

Constructors

InputObjectType Name (Maybe Text) (HashMap Name InputField)

Instances

Eq InputObjectType

Defined in Language.GraphQL.Type.In

Methods

(==) :: InputObjectType -> InputObjectType -> Bool

(/=) :: InputObjectType -> InputObjectType -> Bool

Show InputObjectType

Defined in Language.GraphQL.Type.In

Methods

showsPrec :: Int -> InputObjectType -> ShowS

show :: InputObjectType -> String

showList :: [InputObjectType] -> ShowS

data Type

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).

NamedEnumType EnumType
