Pull Request Overview
This PR refactors the flashblocks context handling in the payload builder to improve immutability and reduce state mutation. The main change involves modifying build_payload to construct a new FlashblocksExtraCtx for each flashblock rather than mutating a shared context.
- Refactored
build_next_flashblockto return new context instead of mutating existing one - Extracted common payload builder context creation into a dedicated method
- Cleaned up imports and removed unused variables

we could also add
FlashblocksExtraCtx::from_config to simplify it too

since Default is implemented on FlashblocksExtraCtx I replaced the empty fields w ..Default::default()

We need to check that it's okay. AFAIK if future is completed before we get engine_getPayload it won't return result to it

How to check it:
make it so rollup-boost can't connect to flashblocks enpoint (or disable flashblocks for it)
It will fallback to getPayload

i tested this by removing --flashblocks.enabled for rollup-boost in builder-playground and running with telemetry, everything appears to be the same as before, what should i be looking for specifically to confirm?

Also let's make FlashblocksExtraCtx::produce_next(FlashblocksExtraCtx)?

Seems good! |
