}sentryfasthttp accepts a struct of Options that allows you to configure how the handler will behave.
Currently it respects 3 options:
// Repanic configures whether Sentry should repanic after recovery, in most cases it should be set to false,
// as fasthttp doesn't include it's own Recovery handler.
Repanic bool
// WaitForDelivery configures whether you want to block the request before moving forward with the response.
// Because fasthttp doesn't include it's own `Recovery` handler, it will restart the application,
// and event won't be delivered otherwise.
WaitForDelivery bool
// Timeout for the event delivery requests.
Timeout time.Durationsentryfasthttp attaches an instance of *sentry.Hub (https://pkg.go.dev/github.com/getsentry/sentry-go#Hub) to the request's context, which makes it available throughout the rest of the request's lifetime.
You can access it by using the sentryfasthttp.GetHubFromContext() method on the context itself in any of your proceeding middleware and routes.
And it should be used instead of the global sentry.CaptureMessage, sentry.CaptureException, or any other calls, as it keeps the separation of data between the requests.
Keep in mind that *sentry.Hub won't be available in middleware attached before to sentryfasthttp!
