Implementation notes
|
|
--------------------
|
|
|
|
- Inline buses use a dedicated implementation so the JIT can inline the channel dispatch path.
|
|
- Non-cancelable, all-sync channels build a priority-ordered multicast dispatcher when subscriptions change.
|
|
- ShrinkPostResult stores Accepted/Handled/Canceled/Failure in one 32-bit value.
|
|
- Generic bus slots and handler snapshots are published with release semantics and read without a publish lock.
|
|
- Mixed sync/async channels, cancelable events, queued schedulers and PostAsync retain the full semantic path.
|
|
|
|
Results are local editor measurements, not cross-device guarantees. The supplied MessagePipe chart was
|
|
produced by a different runtime and machine; the class-payload comparison only establishes the same
|
|
order of throughput. Recheck on the target Player and hardware before release.
