Types ¶
type MultiError ¶
type MultiError struct {
// contains filtered or unexported fields
}
MultiError is a mechanism for capturing errors from parallel go-routines. Usage:
errs := NewMultiError(3)
do := func(f foo) error {...}
for foo in range foos {
go errs.capture(do(foo))
}
// Wait for completion
Will gather all errors returned in a MultiError, which in turn will behave as a normal error.
func NewMultiError ¶
func NewMultiError(max int) *MultiError
NewMultiError creates a new MultiError struct.
func (*MultiError) Add ¶
func (me *MultiError) Add(err error)
Add captures an error from a go-routine and adds it to the MultiError.
func (*MultiError) Err ¶
func (me *MultiError) Err() error
Err returns an non-nil error representing all reported errors. Err returns nil when no errors where reported.
func (*MultiError) Error ¶
func (me *MultiError) Error() string
Error returns a string version of the MultiError. This implements the error interface.
