pub enum ChainResult<T, R> {
Next(T),
Done(R),
}
Expand description
Result of a handler.
This is used to decide if the chain should continue to the next handler or stop and return the result:
- If the chain should continue, the handler should return
ChainResult::Next
. This will traverse the next handler in the chain. - If the chain should stop, the handler should return
ChainResult::Done
. All subsequent chain elements are skipped and the result is returned.
