Multiple Error aggregator for Go.
|
|
|
|
## Usage
|
|
|
|
```go
|
|
func foo() error {
|
|
merr := merror.New()
|
|
|
|
if err := DoSomething(); err != nil {
|
|
merr.Append(err)
|
|
}
|
|
|
|
return merr.ErrorOrNil()
|
|
}
|
|
```
|
|
|
|
A bounded `merror` can be used to guard against memory ballooning.
|
|
|
|
```go
|
|
func bar() error {
|
|
merr := merror.NewWithCap(10)
|
|
|
|
for i := 0; i < 15; i++ {
|
|
if err := DoSomething(); err != nil {
|
|
merr.Append(err)
|
|
}
|
|
}
|
|
|
|
fmt.Printf("Len: %d, Overflow: %d", merr.Len(), merr.Overflow())
|
|
// Len: 10, Overflow: 5
|
|
|
|
return merr.ErrorOrNil()
|
|
}
|
|
```
|
|
|
|
## errors.Is
|
|
|
|
If any of the errors appended to a `merror` match the target error passed to `errors.Is(err, target error)` then true is returned.
|
|
|
|
## errors.As
|
|
|
|
If any of the errors appended to a `merror` match the target type passed to `errors.As(err error, target any)` then true is returned and the target is set to the matching error.
