Functions

func Iter

func Iter(err error, f func(err error))

Iter iterates over an error tree.

It explores the tree recursively, and calls f for each non-nil error.

func Unwrap

func Unwrap(err error) ([]error, error)

Unwrap unwraps an error.

If the error implements `Unwrap() error`, it returns the unwrapped error. If the error implements `Unwrap() []error`, it returns the unwrapped errors. Otherwise, it returns nil.
