Kouhei Sutou commented on ARROW-2487:
-------------------------------------
There is already one use case.
C GLib bindings use {{gboolean}} for boolean value. {{bool}} in C99 is 1byte.
So we can use {{bool}} value for the current {{valid_bytes}}. But {{gboolean}}
isn't 1byte. It uses {{int}} (*1) as the real type.
(*1) https://developer.gnome.org/glib/stable/glib-Basic-Types.html#gboolean
If {{AppendValues}} accepts {{const int*}} for {{valid_bytes}}, we can remove
type conversion ({{gboolean}} -> {{uint8_t}}) from C GLib bindings.
> [C++] Provide a variant of AppendValues that takes bytemaps for the
> nullability
