Functions

func DescriptorOf

func DescriptorOf(msg Described) (*descriptor.DescriptorProto, error)

DescriptorOf returns the descriptor for a given proto message.

func GetFileDescriptor

func GetFileDescriptor(data []byte) (*descriptor.FileDescriptorProto, error)

func OneOf

func OneOf(v interface{}) interface{}

OneOf returns the value of a oneof proto field. For example, given the proto:

message M {
  oneof o {
    A a = 1;
    B b = 2;
    C c = 3;
  }
}

OneOf(m.o) will return either a, b, c or nil, skipping the wrapper struct.

Types

type Described

type Described interface {
	Descriptor() ([]byte, []int)
}

Described is the interface to something that self describes with a compressed FileDescriptorProto.
