Instance methods

full_blocks(chromosome : String, start : Int64, stop : Int64, *, cancelled : Proc(Bool) | Nil = nil) : Int64 | Nil

Returns nil when the precision of every stored block cannot be proved.

cancelled is evaluated between index I/O chunks. It cannot interrupt an in-flight source read, but lets callers abandon a long-running query before the next chunk is processed.
