func GenerateCode

func GenerateCode(data *Data) error

Types

type ArgSet

type ArgSet struct {
	Args     []*FieldArgument
	FuncDecl string
}

type Data

type Data struct {
	Config          *config.Config
	Schema          *ast.Schema
	SchemaStr       map[string]string
	Directives      map[string]*Directive
	Objects         Objects
	Inputs          Objects
	Interfaces      map[string]*Interface
	ReferencedTypes map[string]*config.TypeReference

	QueryRoot        *Object
	MutationRoot     *Object
	SubscriptionRoot *Object
}

Data is a unified model of the code to be generated. Plugins may modify this structure to do things like implement resolvers or directives automatically (eg grpc, validation)
