package blobpool
// newSlotter creates a helper method for the Billy datastore that returns the
// individual shelf sizes used to store transactions in.
//
// The slotter will create shelves for each possible blob count + some tx metadata
// wiggle room, up to the max permitted limits.
//
// The slotter also creates a shelf for 0-blob transactions. Whilst those are not
// allowed in the current protocol, having an empty shelf is not a relevant use
// of resources, but it makes stress testing with junk transactions simpler.

slotsize += blobSize
finished := slotsize > maxBlobsPerTransaction*blobSize+txMaxSize
