What does this PR try to resolve?

  • resolution-started
  • resolution-finished
  • unit-graph-started
  • unit-graph-finished
  • unit-registered

The first four events are simple log events with elapsed time.

The unit-registered event contains unit metadata and the index, so that unit-started doesn't need to have those. As a result, the timing replay now requires unit-registered events to derive those data.

The log and HTML snapshot also changed to rustfix, which is a bit smaller in size.

Part of #15844

The last commit says it is a refactor but it changes events

Also, what is the intent with count fields? When we bring this to --message-format, I appreciate knowing the unit count for progress purposes but not seeing what we'd use the resolution one for. Tracking the scale of the operation?

Is count needed for the unit graph if we report all units in a well defined scope?

but not seeing what we'd use the resolution one for

Resolution could also be for progress purpose, though if we even end up needing that, it would be horrible.

Some other points:

  • Span event usually has a summary attribute on the end event, and resolution and unit-graph construction are span like events.
  • Having a count is easy for consumer (or us) to validate the completeness of instant/log events.

Though I guess it is easy to add fields later than revert it afterwards. I am fine with dropping them now if that is more desired.

fix(log): fix unit_to_index mapping from bcx
9a238b9 
This also drops unit metadata fields in unit-started event.
The metdata is moved to unit-registered event instead

Resolution could also be for progress purpose, though if we even end up needing that, it would be horrible.

Only if we're then sending out events that line up with that count.

Though maybe the following is sufficient.

Tracking the scale of the operation?
