Module Bench_config

Type of the per-benchmark context, which is initialized by around_benchmark and provided to around_measurement. The value can also be bound in the scope of a let%bench or let%bench_fun using the [@ctx?] attribute, like so:

  let%bench_fun ("my benchmark" [@ctx? ctx]) =
    fun arg -> do_something_expensive ctx arg
  ;;

Argument type which is passed locally to functions on the right-hand-side of let%bench_fun. If this is anything other than unit, let%bench cannot be used.

Function which is run once around each benchmark (defined by let%bench or let%bench_fun) and can perform per-benchmark setup and teardown, and also initialize the benchmark_ctx argument to pass to the around_measurement function and (optionally) the benchmark itself.

Function which is invoked around each "batch" of benchmark runs, and provides arg to the benchmark itself to run. This function can be used to perform per-batch setup and teardown, and also provide a local context value (such as a capability) to the benchmark.
