Overview

Package erriter provides a way to iterate over an error tree.

Index

• func All(err error) iter.Seq[error]
• func FirstKeys[V any](seq iter.Seq2[string, V]) map[string]V
• func Unwrap(err error) ([]error, error)

Functions

func All

func All(err error) iter.Seq[error]

All returns an iter.Seq that iterates over an error tree recursively.

func FirstKeys

func FirstKeys[V any](seq iter.Seq2[string, V]) map[string]V

FirstKeys returns a map built from seq, where the first value is kept for each key.

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.
