Types

	XXX_sizecache        int32    `json:"-"`
}

type LacksNativePermission

type LacksNativePermission struct {
	Address    crypto.Address
	NativeName string
}

func (e *LacksNativePermission) Error() string

func (*LacksNativePermission) ErrorCode

func (e *LacksNativePermission) ErrorCode() *Code

func (*LacksNativePermission) ErrorMessage

type Maybe

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

func (*Maybe) Address

func (m *Maybe) Address(value crypto.Address, err error) crypto.Address

func (*Maybe) BigInt

func (m *Maybe) BigInt(value *big.Int, err error) *big.Int

func (*Maybe) Bool

func (m *Maybe) Bool(value bool, err error) bool

func (*Maybe) Bytes

func (m *Maybe) Bytes(value []byte, err error) []byte

func (*Maybe) Error

func (m *Maybe) Error() error

func (*Maybe) PushError

func (m *Maybe) PushError(err error) bool

Errors pushed to state may end up in TxExecutions and therefore the merkle state so it is essential that errors are deterministic and independent of the code path taken to execution (e.g. replay takes a different path to that of normal consensus reactor so stack traces may differ - as they may across architectures)

func (*Maybe) Uint64

func (m *Maybe) Uint64(value uint64, err error) uint64

func (*Maybe) Void

func (m *Maybe) Void(err error)

type NestedCallError

type NestedCallError struct {
	CodedError
	Caller     crypto.Address
	Callee     crypto.Address
	StackDepth uint64
}

func (NestedCallError) Error

func (err NestedCallError) Error() string

type PermissionDenied

type PermissionDenied struct {
	Address crypto.Address
	Perm    permission.PermFlag
}

func (PermissionDenied) Error

func (err PermissionDenied) Error() string

func (PermissionDenied) ErrorCode

func (err PermissionDenied) ErrorCode() *Code

type Sink

type Sink interface {
	// Push an error to the error. If a nil error is passed then that value should not be pushed. Returns true iff error
	// is non nil.
	PushError(error) bool
}

Error sinks are useful for recording errors but continuing with computation. Implementations may choose to just store the first error pushed and ignore subsequent ones or they may record an error trace. Pushing a nil error should have no effects.

type Source

type Source interface {
	// Returns the an error if errors occurred some execution or nil if none occurred
	Error() error
}
