Hi Substrate Community,
is there any way to get the current block weight? This is especially useful, when deciding in on_finalize if there is space left to put in some logic. I know, that on_finalize is guaranteed to run, but I would only run if a block is not full.
How can I manage to do this with Substrate?
I already tried to look into the transaction_payment and frame_system pallet. I could find a BlockWeights struct, but it hasn't the current block weight inside it.
The on_idle hook is probably closer to what you are looking for.
It gets the remaining weight passed into it like this:
fn on_idle(block: T::BlockNumber, remaining: Weight) -> Weight
This happens after all normal transactions and before on_finalize.
on_idle? It gets the remaining weight passed in.
