# go-retry
Simple package to do retries in Go.
You can consider this a practice of *fluent API* in Go.
Maybe used to abstract away of the retry logic so you wont deal with time
calculations at domain level tests.
```go
// complicated.go
type ComplicatedService struct {
retry goretry.Retryer[any]
}
func (s *ComplicatedService) Do() error {
return retry.Retry(func () error {
// do something
})
}
// complicated_test.go
func TestReallyHardWithoutRetryLogic(t *testing.T) {
service := &ComplicatedService{
// So your test will simple call code until success
retry: goretry.New[any](
goretry.WithInitialDelay(0)
),
}
}
```
## Example
```go
retryer := goretry.New[int](
goretry.WithInitialDelay(time.Second),
goretry.WithIncreasingDelay(time.Second),
)
error := retryer.Retry(func() error {
// some loginc
})
result, error := retryer.RetryReturn(func() (int, error) {
// some logic
return value
})
```
More examples can be found in [tests](./retry_test.go).
You also can combine `DelayCalculators`,
examples are in [tests](./delay_test.go).
