can_match.h File Reference

Detailed Description

Free function that decides whether a ChannelRequest can be served by a driver's published capability data (#3186).

The function operates purely on data: a DriverCapabilities snapshot

• a span of PinGroup descriptors + a ChannelRequest. No IChannelDriver instance is required, which makes the compatibility matrix testable in isolation against synthetic fixtures.

IChannelDriver::canMatch() default-implements to this function; the Channel Manager's resolver calls it directly against cached driver snapshots to avoid per-channel virtual dispatch.
