func Is(any Any, v interface{}) bool
Is returns true if the type of the Any is the same as v.
func Register(v interface{}, args ...string)
Register a type with a base URL for JSON marshaling. When the MarshalAny and UnmarshalAny functions are called they will treat the Any type value as JSON. To use protocol buffers for handling the Any value the proto.Register function should be used instead of this function.
func TypeURL(v interface{}) (string, error)
TypeURL returns the type url for a registered type.
func UnmarshalAny(any Any) (interface{}, error)
UnmarshalAny unmarshals the any type into a concrete type.
func UnmarshalByTypeURL(typeURL string, value []byte) (interface{}, error)
UnmarshalByTypeURL unmarshals the given type and value to into a concrete type.
func UnmarshalTo(any Any, out interface{}) error
UnmarshalTo unmarshals the any type into a concrete type passed in the out argument. It is identical to UnmarshalAny, but lets clients provide a destination type through the out argument.
func UnmarshalToByTypeURL(typeURL string, value []byte, out interface{}) error
UnmarshalToByTypeURL unmarshals the given type and value into a concrete type passed in the out argument. It is identical to UnmarshalByTypeURL, but lets clients provide a destination type through the out argument.
Any contains an arbitrary protcol buffer message along with its type.
While there is google.golang.org/protobuf/types/known/anypb.Any, we'd like to have our own to hide the underlying protocol buffer implementations from containerd clients.
https://developers.google.com/protocol-buffers/docs/proto3#any
type Any interface {
// GetTypeUrl returns a URL/resource name that uniquely identifies
// the type of the serialized protocol buffer message.
GetTypeUrl() string
// GetValue returns a valid serialized protocol buffer of the type that
// GetTypeUrl() indicates.
GetValue() []byte
}
func MarshalAny(v interface{}) (Any, error)
MarshalAny marshals the value v into an any with the correct TypeUrl. If the provided object is already a proto.Any message, then it will be returned verbatim. If it is of type proto.Message, it will be marshaled as a protocol buffer. Otherwise, the object will be marshaled to json.
