NAME

GraphQL::Type::Library - GraphQL type library

SYNOPSIS

    use GraphQL::Type::Library -all;
    has name => (is => 'ro', isa => StrNameValid, required => 1);

DESCRIPTION

Provides Type::Tiny types.

TYPES

StrNameValid

If called with a string that is not a valid GraphQL name, will throw an exception. Suitable for passing to an isa constraint in Moo.

ValuesMatchTypes

Subtype of "HashRef" in Types::Standard, whose values are hash-refs. Takes two parameters:

value keyname

Optional within the second-level hashes.

type keyname

Values will be a GraphQL::Type. Mandatory within the second-level hashes.

In the second-level hashes, the values (if given) must pass the GraphQL type constraint.

FieldMapInput

Hash-ref mapping field names to a hash-ref description. Description keys, all optional except type:

type

GraphQL input type for the field.

default_value

Default value for this argument if none supplied. Must be same type as the type (implemented with type "ValuesMatchTypes".

description

Description.

FieldMapOutput

Hash-ref mapping field names to a hash-ref description. Description keys, all optional except type:

type

GraphQL output type for the field.

args

A "FieldMapInput".

resolve

Code-ref to return a given property from a given source-object.

subscribe

Code-ref to return a given property from a given source-object.

deprecation_reason

Reason if deprecated. If given, also sets a boolean key of is_deprecated to true.

description

Description.

Int32Signed

32-bit signed integer.

ArrayRefNonEmpty

Like "ArrayRef" in Types::Standard but requires at least one entry.

UniqueByProperty

An ArrayRef, its members' property (the one in the parameter) can occur only once.

  use Moo;
  use GraphQL::Type::Library -all;
  has types => (
    is => 'ro',
    isa => UniqueByProperty['name'] & ArrayRef[InstanceOf['GraphQL::Type::Object']],
    required => 1,
  );

ExpectObject

A Maybe[HashRef] that produces a GraphQL-like message if it fails, saying "found not an object".
