errset is a trivial golang package that implements a slice of errors.
The typical go idiom is to return an error or a tuple of (thing, error) from functions. This works well if a function performs exactly one task, but
when a function does work which can reasonably partially fail, I found myself writing the same code over and over again. For example:
// CommitBatch commits as many things as it can.
func CommitBatch(things []Thing) error {
errs := errset.ErrSet{}
for _, thing := range things {
err := Commit(thing)
if err != nil {
errs = append(errs, err)
}
}
return errs.ReturnValue() // nil if there were no errors
}

Types ¶
type ErrSet ¶
type ErrSet []error
ErrSet represents a list of errors.
Example:
errs := ErrSet{}
for ... {
if err := DoSomething(i); err != nil {
errs = append(errs, err)
}
}
return errs.ReturnValue()
func (ErrSet) Error ¶
Error implements the error interface. It returns each error in the list concatenated together with "; ".
func (ErrSet) ReturnValue ¶
ReturnValue returns the ErrSet object if at least one non-nill error is present or nil if there are no errors
