Types

type Actor

type Actor struct {
	Code   *cid.Cid
	Memory *cid.Cid
	Nonce  uint64
}

type CallContext

type CallContext struct {
	Ctx           context.Context
	From          types.Address
	FromNonce     uint64
	State         *State
	ContractState *ContractState
	Address       types.Address
}

CallContext is information accessible to the contract during a given invocation

type Contract

type Contract interface {
	Call(ctx *CallContext, method string, args []interface{}) (interface{}, error)
}

type ContractState

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

func (*ContractState) Flush

func (cs *ContractState) Flush(ctx context.Context) (*cid.Cid, error)

func (*ContractState) Get

func (cs *ContractState) Get(ctx context.Context, k string) ([]byte, error)

func (*ContractState) Node

func (cs *ContractState) Node() *hamt.Node

func (*ContractState) Set

func (cs *ContractState) Set(ctx context.Context, k string, val []byte) error

type State

func (*State) SetActor

func (s *State) SetActor(ctx context.Context, a types.Address, act *Actor) error

type ToychainTokenContract

type ToychainTokenContract struct{}

func (*ToychainTokenContract) Call

func (ftc *ToychainTokenContract) Call(ctx *CallContext, method string, args []interface{}) (interface{}, error)
