A Go package for managing the registration, marshaling, and unmarshaling of encoded types.
This package helps when types are sent over a ttrpc/GRPC API and marshaled as a protobuf [Any](https://pkg.go.dev/google.golang.org/protobuf@v1.27.1/types/known/anypb#Any)

package typeurl
// Package typeurl assists with managing the registration, marshaling, and
// unmarshaling of types encoded as protobuf.Any.
//
// A protobuf.Any is a proto message that can contain any arbitrary data. It
// consists of two components, a TypeUrl and a Value, and its proto definition
// looks like this:
//
// message Any {
// string type_url = 1;
// bytes value = 2;
// }
//
// The TypeUrl is used to distinguish the contents from other proto.Any
// messages. This typeurl library manages these URLs to enable automagic
// marshaling and unmarshaling of the contents.
//
// For example, consider this go struct:
//
// type Foo struct {
// Field1 string
// Field2 string
// }
//
// To use typeurl, types must first be registered. This is typically done in
// the init function
//
// func init() {
// typeurl.Register(&Foo{}, "Foo")
// }
//
// This will register the type Foo with the url path "Foo". The arguments to
// Register are variadic, and are used to construct a url path. Consider this
// example, from the github.com/containerd/containerd/client package:
//
// func init() {
// const prefix = "types.containerd.io"
// // register TypeUrls for commonly marshaled external types
// major := strconv.Itoa(specs.VersionMajor)
// typeurl.Register(&specs.Spec{}, prefix, "opencontainers/runtime-spec", major, "Spec")
// // this function has more Register calls, which are elided.
// }
//
// This registers several types under a more complex url, which ends up mapping
// to `types.containerd.io/opencontainers/runtime-spec/1/Spec` (or some other
// value for major).
//
// Once a type is registered, it can be marshaled to a proto.Any message simply
// by calling `MarshalAny`, like this:
//
// foo := &Foo{Field1: "value1", Field2: "value2"}
// anyFoo, err := typeurl.MarshalAny(foo)
//
// MarshalAny will resolve the correct URL for the type. If the type in
// question implements the proto.Message interface, then it will be marshaled
// as a proto message. Otherwise, it will be marshaled as json. This means that
// typeurl will work on any arbitrary data, whether or not it has a proto
// definition, as long as it can be serialized to json.
//
// To unmarshal, the process is simply inverse:
//
// iface, err := typeurl.UnmarshalAny(anyFoo)
// foo := iface.(*Foo)
//
// The correct type is automatically chosen from the type registry, and the
// returned interface can be cast straight to that type.
