Functions ¶
func Failf ¶
func Failf(format string, args ...interface{})
Failf formats the arguments according to format, prints the result to stderr, and exits.
func IfError ¶
IfError prints err to stderr if the error is non-nil. Extra arguments are converted to a string which, if present, annotates the error. Returns true if the error is non-nil.
func IfErrorf ¶
IfErrorf prints err to stderr if the err is non-nil. Extra arguments are formatted as a string, according to the format argument. If present, this string annotates the error. Returns true if the error is non-nil.
func IfFatal ¶
func IfFatal(err error, args ...interface{})
IfFatal prints err to stderr and exits, if the error is non-nil. Extra arguments are converted to a string which, if present, annotates the error.
Types ¶
type Errors ¶
type Errors struct {
// Msg is an optional message to be displayed before the list of errors.
Msg string
// Errs is the list of errors.
Errs []error
}
Errors groups together multiple errors as a single error.
