Functions

func ABCIError

func ABCIError(codespace string, code uint32, log string) error

ABCIError will resolve an error code/log from an abci result into an error message. If the code is registered, it will map it back to the canonical error, so we can do eg. ErrNotFound.Is(err) on something we get back from an external API.

This should *only* be used in clients, not in the server side. The server (abci app / blockchain) should only refer to registered errors

func ABCIInfo

func ABCIInfo(err error, debug bool) (codespace string, code uint32, log string)

ABCIInfo returns the ABCI error information as consumed by the tendermint client. Returned codespace, code, and log message should be used as a ABCI response. Any error that does not provide ABCICode information is categorized as error with code 1, codespace UndefinedCodespace When not running in a debug mode all messages of errors that do not provide ABCICode information are replaced with generic "internal error". Errors without an ABCICode information as considered internal.

func IsOf

func IsOf(received error, targets ...error) bool

IsOf checks if a received error is caused by one of the target errors. It extends the errors.Is functionality to a list of errors.

func QueryResult

func QueryResult(err error) abci.ResponseQuery

QueryResult returns a ResponseQuery from an error. It will try to parse ABCI info from the error.

func Recover

func Recover(err *error)

Recover captures a panic and stop its propagation. If panic happens it is transformed into a ErrPanic instance and assigned to given error. Call this function using defer in order to work as expected.

func Redact

func Redact(err error) error

Redact replaces an error that is not initialized as an ABCI Error with a generic internal error instance. If the error is an ABCI Error, that error is simply returned.

func ResponseCheckTx

func ResponseCheckTx(err error, gw, gu uint64, debug bool, events []abci.Event) abci.ResponseCheckTx

ResponseCheckTx returns an ABCI ResponseCheckTx object with fields filled in from the given error and gas values.

func ResponseDeliverTx

func ResponseDeliverTx(err error, gw, gu uint64, debug bool, events []abci.Event) abci.ResponseDeliverTx

ResponseDeliverTx returns an ABCI ResponseDeliverTx object with fields filled in from the given error and gas values.

func WithType

func WithType(err error, obj interface{}) error

WithType is a helper to augment an error with a corresponding type message

func Wrap

func Wrap(err error, description string) error

Wrap extends given error with an additional information.

If the wrapped error does not provide ABCICode method (ie. stdlib errors), it will be labeled as internal error.

If err is nil, this returns nil, avoiding the need for an if statement when wrapping a error returned at the end of a function

func Wrapf

func Wrapf(err error, format string, args ...interface{}) error

Wrapf extends given error with an additional information.

This function works like Wrap function with additional functionality of formatting the input as specified.

Types

type Error

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

Error represents a root error.

Weave framework is using root error to categorize issues. Each instance created during the runtime should wrap one of the declared root errors. This allows error tests and returning all errors to the client in a safe manner.

All popular root errors are declared in this package. If an extension has to declare a custom root error, always use Register function to ensure error code uniqueness.

func New

func New(codespace string, code uint32, desc string) *Error

func Register

func Register(codespace string, code uint32, description string) *Error

Register returns an error instance that should be used as the base for creating error instances during runtime.

Popular root errors are declared in this package, but extensions may want to declare custom codes. This function ensures that no error code is used twice. Attempt to reuse an error code results in panic.

Use this function only during a program startup phase.

func (Error) ABCICode

func (e Error) ABCICode() uint32

func (Error) Codespace

func (e Error) Codespace() string

func (Error) Error

func (e Error) Error() string

func (*Error) Is

func (e *Error) Is(err error) bool

Is check if given error instance is of a given kind/type. This involves unwrapping given error using the Cause method if available.

func (Error) Wrap

func (e Error) Wrap(desc string) error

Wrap extends this error with an additional information. It's a handy function to call Wrap with sdk errors.

func (Error) Wrapf

func (e Error) Wrapf(desc string, args ...interface{}) error

Wrapf extends this error with an additional information. It's a handy function to call Wrapf with sdk errors.
