Functions ¶
func Chain ¶
Chain executes functions in chain and if one of them return error this function stop chain execution and return this error
Example ¶
f1 := func() error { return nil }
f2 := func() error { return nil }
f3 := func() error { return fmt.Errorf("Error 3") }
f4 := func() error { return fmt.Errorf("Error 4") }
err := Chain(f1, f2, f3, f4)
fmt.Println(err.Error())
Output: Error 3
Types ¶
type Errors ¶
type Errors struct {
// contains filtered or unexported fields
}
Errors is struct for handling many errors at once
Example ¶
f1 := func() error { return nil }
f2 := func() error { return nil }
f3 := func() error { return fmt.Errorf("Error 3") }
f4 := func() error { return fmt.Errorf("Error 4") }
errs := NewErrors()
errs.Add(f1())
errs.Add(f2())
errs.Add(f3())
errs.Add(f4())
fmt.Printf("Last error text: %v\n", errs.Last().Error())
fmt.Printf("Number of errors: %d\n", errs.Num())
fmt.Printf("Has errors: %t\n", errs.HasErrors())
Output: Last error text: Error 4 Number of errors: 2 Has errors: true
