Functions

func Combine

func Combine(desc string, e ...error) error

Combine returns the composite of all non-nil errors in the input, with the given text description added for context.

func First

func First(desc string, e ...error) error

First returns the first non-nil error given in the input, wrapped with the given description string. If there isn't one, First returns nil.

func RootCause

func RootCause(e error) error

RootCause gets the ultimate root cause error out of a wrapped error. If the given error is not a wrapped error, the input is returned as-is.

func Wrap

func Wrap(desc string, e error) error

Wrap simply wraps an existing error with some context.
