Async directory operations — create, remove, read, link, rename.

Wraps low-level std/sys/dir with typed APIs using the Exception effect.

Example

{ create_dir, remove_dir, read_dir } :: import "std/fs/dir";
{ Path } :: import "std/path";

main :: (fn(io : Io, exn : Exception) -> unit)({
  io.await(create_dir(Path.new(`/tmp/yo_test`), io), { io, exn });
  entries := io.await(read_dir(Path.new(`/tmp/yo_test`), io), { io, exn });
  io.await(remove_dir(Path.new(`/tmp/yo_test`), io), { io, exn });
});
