Dion is correct, but it's ->cap, rather than ->caps. And edit_post is a meta
cap, not a primitive cap, so you'd need to also pass the post ID so
WordPress can check what actual capabilities are required.

So:
$post_type_object = get_post_type_object( $post->post_type );
if ( current_user_can( $post_type_object->cap->edit_post, $post->ID ) ) {
... }
