Function ncursesw::menu::set_menu_spacing

pub fn set_menu_spacing(
    menu: Option<MENU>, 
    menu_spacing: MenuSpacing
) -> Result<(), NCurseswMenuError>

Sets the spacing information for the menu. Its parameter MenuSpacing::spc_description controls the number of spaces between an item name and an item description. It must not be larger than TABSIZE. The menu system puts in the middle of this spacing area the pad character. The remaining parts are filled with spaces. The MenuSpacing::spc_rows parameter controls the number of rows that are used for an item. It must not be larger than 3. The menu system inserts the blank lines between item rows, these lines will contain the pad character in the appropriate positions. The MenuSpacing::spc_columns parameter controls the number of blanks between columns of items. It must not be larger than TABSIZE. A value of 0 for all the spacing values resets them to the default, which is 1 for all of them.

If menu is None then the default value is set.
