Package multierr provides a simple way of handling multiple errors and consolidating them into a single error.
|
|
|
|
Example:
|
|
|
|
package main
|
|
|
|
import (
|
|
`r00t2.io/goutils/multierr`
|
|
)
|
|
|
|
func main() {
|
|
|
|
var err error
|
|
var errs []error
|
|
|
|
errs = make([]error, 0)
|
|
|
|
for _, i := range someSlice {
|
|
go func() {
|
|
if err = i.DoSomething(); err != nil {
|
|
errs = append(errs, err)
|
|
}
|
|
}()
|
|
}
|
|
|
|
if errs != nil && len(errs) != 0 {
|
|
// err now contains multiple errors presented as a single error.
|
|
err = multierr.NewErrors(errs...)
|
|
}
|
|
}
|
|
|
|
MultiError also has a shorthand, making the above much less verbose:
|
|
|
|
package main
|
|
|
|
import (
|
|
`r00t2.io/goutils/multierr`
|
|
)
|
|
|
|
func main() {
|
|
|
|
var err error
|
|
var multierror *multierr.MultiError = multierr.NewMultiError(nil)
|
|
|
|
for _, i := range someSlice {
|
|
go func() {
|
|
if err = i.DoSomething(); err != nil {
|
|
multierror.AddError(err)
|
|
}
|
|
}()
|
|
}
|
|
// multierror now contains any/all errors above.
|
|
}
|
|
|
|
In the above, the multierror assignment can still be used as an error.
