type Any 

type Any struct {

	// nolint
	TypeUrl string `protobuf:"bytes,1,opt,name=type_url,json=typeUrl,proto3" json:"type_url,omitempty"`
	// Must be a valid serialized protocol buffer of the above specified type.
	Value []byte `protobuf:"bytes,2,opt,name=value,proto3" json:"value,omitempty"`

	// nolint
	XXX_NoUnkeyedLiteral struct{} `json:"-"`

	// nolint
	XXX_unrecognized []byte `json:"-"`

	// nolint
	XXX_sizecache int32 `json:"-"`
	// contains filtered or unexported fields
}

func NewAnyWithCustomTypeURL 

func NewAnyWithCustomTypeURL(v proto.Message, typeURL string) (*Any, error)

NewAnyWithCustomTypeURL same as NewAnyWithValue, but sets a custom type url, instead using the one from proto.Message. NOTE: This functions should be only used for types with additional logic bundled into the protobuf Any serialization. For simple marshaling you should use NewAnyWithValue.

func NewAnyWithValue 

func NewAnyWithValue(v proto.Message) (*Any, error)

NewAnyWithValue constructs a new Any packed with the value provided or returns an error if that value couldn't be packed. This also caches the packed value so that it can be retrieved from GetCachedValue without unmarshaling

func NewPopulatedAny 

func NewPopulatedAny(r randyAny, easy bool) *Any

func UnsafePackAny 

func UnsafePackAny(x interface{}) *Any

UnsafePackAny packs the value x in the Any and instead of returning the error in the case of a packing failure, keeps the cached value. This should only be used in situations where compatibility is needed with amino. Amino-only values can safely be packed using this method when they will only be marshaled with amino and not protobuf.

func (*Any) XXX_MessageName 

func (*Any) XXX_MessageName() string

func (*Any) XXX_WellKnownType() string

type AnyUnpacker 

type AnyUnpacker interface {
	// UnpackAny unpacks the value in any to the interface pointer passed in as
	// iface. Note that the type in any must have been registered in the
	// underlying whitelist registry as a concrete type for that interface
	// Ex:
	//    var msg sdk.Msg
	//    err := cdc.UnpackAny(any, &msg)
	//    ...
	UnpackAny(any *Any, iface interface{}) error
}

AnyUnpacker is an interface which allows safely unpacking types packed in Any's against a whitelist of registered types

type InterfaceRegistry 

type InterfaceRegistry interface {
	AnyUnpacker
	jsonpb.AnyResolver

	// RegisterInterface associates protoName as the public name for the
	// interface passed in as iface. This is to be used primarily to create
	// a public facing registry of interface implementations for clients.
	// protoName should be a well-chosen public facing name that remains stable.
	// RegisterInterface takes an optional list of impls to be registered
	// as implementations of iface.
	//
	// Ex:
	//   registry.RegisterInterface("creata.base.v1beta1.Msg", (*sdk.Msg)(nil))
	RegisterInterface(protoName string, iface interface{}, impls ...proto.Message)

	// RegisterImplementations registers impls as concrete implementations of
	// the interface iface.
	//
	// Ex:
	//  registry.RegisterImplementations((*sdk.Msg)(nil), &MsgSend{}, &MsgMultiSend{})
	RegisterImplementations(iface interface{}, impls ...proto.Message)

	// RegisterCustomTypeURL allows a protobuf message to be registered as a
	// google.protobuf.Any with a custom typeURL (besides its own canonical
	// typeURL). iface should be an interface as type, as in RegisterInterface
	// and RegisterImplementations.
	//
	// Ex:
	// This will allow us to pack service methods in Any's using the full method name
	// as the type URL and the request body as the value, and allow us to unpack
	// such packed methods using the normal UnpackAny method for the interface iface.
	RegisterCustomTypeURL(iface interface{}, typeURL string, impl proto.Message)

	// ListAllInterfaces list the type URLs of all registered interfaces.
	ListAllInterfaces() []string

	// ListImplementations lists the valid type URLs for the given interface name that can be used
	// for the provided interface type URL.
	ListImplementations(ifaceTypeURL string) []string
}

InterfaceRegistry provides a mechanism for registering interfaces and implementations that can be safely unpacked from Any

func NewInterfaceRegistry 

func NewInterfaceRegistry() InterfaceRegistry

NewInterfaceRegistry returns a new InterfaceRegistry

type ProtoJSONPacker 

type ProtoJSONPacker struct {
	JSONPBMarshaler *jsonpb.Marshaler
}

ProtoJSONPacker is an AnyUnpacker provided for compatibility with jsonpb

func (ProtoJSONPacker) UnpackAny 

func (a ProtoJSONPacker) UnpackAny(any *Any, _ interface{}) error

type UnpackInterfacesMessage 

type UnpackInterfacesMessage interface {
	// UnpackInterfaces is implemented in order to unpack values packed within
	// Any's using the AnyUnpacker. It should generally be implemented as
	// follows:
	//   func (s *MyStruct) UnpackInterfaces(unpacker AnyUnpacker) error {
	//		var x AnyInterface
	//		// where X is an Any field on MyStruct
	//		err := unpacker.UnpackAny(s.X, &x)
	//		if err != nil {
	//			return nil
	//		}
	//		// where Y is a field on MyStruct that implements UnpackInterfacesMessage itself
	//		err = s.Y.UnpackInterfaces(unpacker)
	//		if err != nil {
	//			return nil
	//		}
	//		return nil
	//	 }
	UnpackInterfaces(unpacker AnyUnpacker) error
}

UnpackInterfacesMessage is meant to extend protobuf types (which implement proto.Message) to support a post-deserialization phase which unpacks types packed within Any's using the whitelist provided by AnyUnpacker
