Functions

func AsPqError

func AsPqError(err error) (*pq.Error, bool)

func Dump

func Dump(w io.Writer, err error)

Dump will dump the formatted error string (with each error in its own line) into w io.Writer

func Errorf

func Errorf(be BaseError, a ...interface{}) error

func Is

func Is(err error, target error, targets ...error) bool

Is reports whether any error in err's chain matches the target(s). Exactly the same as errors.Is, but variadic

func S1dump

func S1dump(err error) string

S1dump will return the raw error string (the entire error stack trace in one line)

func Sdump

func Sdump(err error) string

Sdump will return the formatted error string (with each error in its own line)

func Wrap

func Wrap(err error) error

Wrap will wrap an error and return a new error that is annotated with the function/file/linenumber of where Wrap() was called

Types

type BaseError

type BaseError string

func (BaseError) Error

func (e BaseError) Error() string

func (BaseError) PqCode

func (e BaseError) PqCode() pq.ErrorCode

The first five characters of the error string are assumed to be a postgres error code

type Error

type Error struct {
	BaseError BaseError
	Args      []interface{}
}

func AsError

func AsError(err error) (*Error, bool)

func (*Error) Error

func (e *Error) Error() string

func (*Error) Unwrap

func (e *Error) Unwrap() error
