Module Int_mark_zipper.On_monadSource
On_monad provides various marked zipper operations parametrised by a monad.
Parameters
module M : Base.Monad.SSignature
include Zipper_types.S_monadic with type 'a t := 'a t with module M := M
pop_m zipper ~on_empty behaves like pop, but executes a custom monadic action on_empty, instead of returning an error, when the cursor is empty.
peek_m ?steps zipper ~on_empty behaves like peek_opt, but executes a custom monadic action on_empty, instead of returning None, when the cursor is empty.
step_m ?steps zipper ~on_empty behaves like step, but executes a custom monadic action on_empty, instead of returning an error, when the cursor is empty.
mark_m zipper ~mark ~on_empty behaves like mark, but executes a custom monadic action on_empty, instead of returning an error, when the cursor is empty.
recall_m zipper ~mark ~on_empty behaves like recall, but executes a custom monadic action on_empty, instead of returning an error, when the mark can't be found.
delete_to_mark_m zipper ~mark ~on_empty behaves like delete_to_mark, but executes a custom monadic action on_empty, instead of returning an error, when the mark can't be found.

'final M.tfold_m_until zipper ~f ~init ~finish behaves like fold_until, except that f and finish, and therefore the function itself, return results inside a monad context.
