type Field

type Field struct {

}

func (Field) IsClass

func (f Field) IsClass() bool

func (Field) IsEnum

func (f Field) IsEnum() bool

func (Field) IsProtocol

type FieldDescriptor

type FieldDescriptorKind

type FieldDescriptorKind uint16

const (
	// Swift nominal types.
	Struct FieldDescriptorKind = iota
	Class
	Enum

	// Fixed-size multi-payload enums have a special descriptor format that
	// encodes spare bits.
	//
	// FIXME: Actually implement this. For now, a descriptor with this kind
	// just means we also have a builtin descriptor from which we get the
	// size and alignment.
	MultiPayloadEnum

	// A Swift opaque protocol. There are no fields, just a record for the
	// type itself.
	Protocol

	// A Swift class-bound protocol.
	ClassProtocol

	// An Objective-C protocol, which may be imported or defined in Swift.
	ObjCProtocol

	// An Objective-C class, which may be imported or defined in Swift.
	// In the former case, field type metadata is not emitted, and
	// must be obtained from the Objective-C runtime.
	ObjCClass
