func Cause(err error) error

Cause returns the underlying cause of the error, if possible.

func Errorf ¶

func Errorf(format string, args ...any) error

Errorf formats according to a format specifier and returns the string as a value that satisfies error. Errorf also records the stack trace at the point it was called.

func HasCause ¶

func HasCause(source, target error) bool

HasCause recursively checks errors wrapped using Wrapf until it detects the target error

func HasType ¶

func HasType(source, target error) bool

HasType recursively checks errors wrapped using Wrapf until it detects the target error type

func Is ¶

func Is(source, target error) bool

Is recursively checks errors wrapped using Wrapf until it detects the target error

func Join ¶ added in v0.6.0

func Join(errs ...error) error

Join returns an error that wraps the given errors.

func New ¶

func New(msg string) error

New returns an error with the supplied message. New also records the stack trace at the point it was called.

func WithStack ¶ added in v0.6.0

func WithStack(err error) error

func Wrap ¶

func Wrapf ¶

func Wrapf(err error, format string, args ...any) error

Wrapf wraps an error in a way compatible with HasCause
