"Core_bench" ============ `Core_bench` is a library for running benchmarks written using the `ppx_bench` syntax extension. See https://blog.janestreet.com/core_bench-micro-benchmarking-for-ocaml/ for the introduction. To run the benchmarks when using `dune`, you usually need to define your own executable that calls `Inline_benchmarks_public.Runner.main`. You need to make sure that the benchmarks are linked into this executable, usually by adding `(link_flags -linkall)` to the executable stanza to make sure the library dependencies are not dropped by the compiler.
