Functions

func Abort

func Abort(code exitcode.ExitCode)

Abort aborts the LegacyVM execution and sets the executing message return to the given `code`.

func Abortf

func Abortf(code exitcode.ExitCode, msg string, args ...interface{})

Abortf will stop the LegacyVM execution and return an the error to the caller.

Types

type CallerPattern

type CallerPattern interface {
	// IsMatch returns "True" if the patterns matches
	IsMatch(ctx PatternContext) bool
}

CallerPattern checks if the caller matches the pattern.

type ExecutionPanic

type ExecutionPanic struct {
	// contains filtered or unexported fields
}

ExecutionPanic is used to abort vm execution with an exit code.

func (ExecutionPanic) Code

func (p ExecutionPanic) Code() exitcode.ExitCode

Code is the code used to abort the execution (see: `Abort()`).

func (ExecutionPanic) String

func (p ExecutionPanic) String() string

type ExtendedInvocationContext

type ExtendedInvocationContext interface {
	InvocationContext

	NewActorAddress() address.Address
	// Create an actor in the state tree.
	//
	// This will allocate an ID address for the actor and call its `Constructor()` method.
	//
	// WARNING: May only be called by InitActor.
	CreateActor(codeID cid.Cid, addr address.Address)

	DeleteActor(beneficiary address.Address)
}

ExtendedInvocationContext is a set of convenience functions built on top external ABI calls.

Actor code should not be using this interface directly.

Note: This interface is intended to document the full set of available operations and ensure the context implementation exposes them.

type InvocationContext

type InvocationContext interface {
	// Runtime exposes some methods on the runtime to the actor.
	Runtime() Runtime
	// Store is the raw store for IPLD objects.
	//
	// Note: this is required for custom data structures.
	Store() rt5.Store
	// Message contains information available to the actor about the executing message.
	Message() rt5.Message
	// ValidateCaller validates the caller against a patter.
	//
	// All actor methods MUST call this method before returning.
	ValidateCaller(CallerPattern)
	// StateHandle handles access to the actor state.
	State() rt5.StateHandle
	// Send allows actors to invoke methods on other actors
	Send(toAddr address.Address, methodNum abi.MethodNum, params cbor.Marshaler, value abi.TokenAmount, out cbor.Er) exitcode.ExitCode
	// Balance is the current balance on the current actors account.
	//
	// Note: the value received for this invocation is already reflected on the balance.
	Balance() abi.TokenAmount
}

InvocationContext is passed to the actors on each method call.

type PatternContext

type PatternContext interface {
	CallerCode() cid.Cid
	CallerAddr() address.Address
}

PatternContext is the context a pattern gets access to in order to determine if the caller matches.

type Runtime

type Runtime interface {
	// CurrentEpoch is the current chain epoch.
	CurrentEpoch() abi.ChainEpoch

	NetworkVersion() network.Version
}

Runtime has operations in the LegacyVM that are exposed to all actors.
