A ReplayTask is a task that isn't writing to the output but follows a resumable path. Most of the code paths will be reused for this type of work.
If we have ResumeSlots we don't have an element key to match them with. This only happens inside an array. If we have any, we can simply pick those children out of the array and resume them by rendering that node normally into the relevant segment.

It's like a combination of ReplaySuspenseBoundary and ResumeElement.

This forks Task into ReplayTask and RenderTask. A RenderTask is the normal mode and it has a segment to write into. A ReplayTask doesn't have a segment to write into because that has already been written but instead it has a ReplayState which keeps track of the next set of paths to follow. Once we hit a "Resume" node we convert it into a RenderTask and continue rendering from there. We can resume at either an Element position or a Slot position. An Element pointing to a component doesn't mean we resume that component, it means we resume in the child position directly below that component. Slots are slots inside arrays. Instead of statically forking most paths, I kept using the same path and checked for the existence of a segment or replay state dynamically at runtime. However, there's still quite a bit of forking here like retryRenderTask and retryReplayTask. Even in the new forks there's a lot of duplication like resumeSuspenseBoundary, replaySuspenseBoundary and renderSuspenseBoundary. There's opportunity to simplify this a bit. DiffTrain build for [a5fc797](a5fc797)

There was a problem hiding this comment.
A child of this boundary may need to render and during that render new styles could be discovered so we'd want to associate those to this boundary. Makes sense to me that this is still needed
