Updates the
AllFlags()
API to gather and expose prerequisite information for flags.The prereqs are available via
State::Prerequisites()
, and are more importantly serialized in the JSON representation of the bootstrap payload.The implementation strategy was to create a custom
IEventProcessor
specifically forAllFlags
usage. Previously,AllFlags
invoked the evaluator with a no-opEventScope
, which made event creation a no-op within the eval algorithm.This change now passes in a
PrereqEventRecorder
which tracks the top-level prerequisites of each flag.
