var Address = func() address.Address {

	addr, err := address.NewIDAddress(98)
	if err != nil {
		panic(err)
	}
	return addr
}()

Address is the singleton address of this actor. Its value is 98 (builtin.FirstNonSingletonActorId - 2), as 99 is reserved for the burnt funds singleton.

Types

type AbortWithArgs 

type AbortWithArgs struct {
	Code         exitcode.ExitCode
	Message      string
	Uncontrolled bool
}

AbortWithArgs are the arguments to the Actor.AbortWith method, specifying the exit code to (optionally) abort with and the message.

func (*AbortWithArgs) MarshalCBOR 

func (t *AbortWithArgs) MarshalCBOR(w io.Writer) error

func (*AbortWithArgs) UnmarshalCBOR 

func (t *AbortWithArgs) UnmarshalCBOR(r io.Reader) (err error)

type Actor 

type Actor struct{}

Actor is a chaos actor. It implements a variety of illegal behaviours that trigger violations of VM invariants. These behaviours are not found in production code, but are important to test that the VM constraints are properly enforced.

The chaos actor is being incubated and its behaviour and ABI be standardised shortly. Its CID is ChaosActorCodeCID, and its singleton address is 98 (Address). It cannot be instantiated via the init actor, and its constructor panics.

Test vectors relying on the chaos actor being deployed will carry selector "chaos_actor:true".

func (Actor) AbortWith 

func (a Actor) AbortWith(rt runtime2.Runtime, args *AbortWithArgs) *abi.EmptyValue

AbortWith simply causes a panic with the passed exit code.

func (Actor) CallerValidation 

func (a Actor) CallerValidation(rt runtime2.Runtime, args *CallerValidationArgs) *abi.EmptyValue

func (Actor) Exports 

func (a Actor) Exports() []interface{}

Exports defines the methods this actor exposes publicly.

func (Actor) InspectRuntime 

func (a Actor) InspectRuntime(rt runtime2.Runtime, _ *abi.EmptyValue) *InspectRuntimeReturn
