Detailed Description

Helper class that detects when a promise is canceled.

Used to detect canceled requests and prevent potential crashes on unclean disconnects.

In the future, this could also be used to support a way for wrapped C++ methods to detect cancellation (like approach #4 in https://github.com/bitcoin/bitcoin/issues/33575).
