Parameters

Signature

type t = {
  1. writer : Def.writer;
  2. store_path : string;
  3. mutable t0 : Mtime_clock.counter;
  4. mutable prev_merge_durations : float list;
  5. mutable commit_before : Def.bag_of_stats * Def.store_before;
}

Imperative stat trace collector. It is optimised to minimise the CPU footprint.
