The OCaml compiler has a bunch of intrinsics for Bigstrings, but they're not widely-known, sometimes misused, and programs that use Bigstrings are slower than they have to be. And even if a library got that part right and exposed the intrinsics properly, the compiler doesn't have any fast blits between Bigstrings and other string-like types.
So here they are. Go crazy.
Install the library and its dependencies via OPAM:
opam install bigstringaf
To install development dependencies, pin the package from the root of the repository:
opam pin add -n bigstringaf . opam install --deps-only bigstringaf
After this, you may install a development version of the library using the install command as usual.
For building and running the tests during development, you will need to install the
opam install alcotest make test
