Functions

func GetTags

func GetTags(err error) []string

Scans all wrapped tags in an error.

func SerializeTags

func SerializeTags(err error) string

Serializes the tags in an error to a single string of constant (known at compile time) cardinality.

func Tag

func Tag(tag string, err error) error

Attaches a tag to an error.

A tag should be a string literal that describes the current function path concisely. It is used for reporting error type in metrics, so a small cardinality is expected.

func TagErrorf

func TagErrorf(tag string, format string, args ...any) error

Shorthand for Errorf + Tag.

func TagWrapf

func TagWrapf(tag string, err error, format string, args ...any) error

Shorthand for Wrapf + Tag.

func Wrapf

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

Wraps an error with context information in the message.
