Function ncursesw::mvwins_nwstr

pub fn mvwins_nwstr(
    handle: WINDOW, 
    origin: Origin, 
    wstr: &WideString, 
    number: i32
) -> Result<(), NCurseswError>

Insert a wide string (as many characters as will fit on the line) before the character at origin, up to number characters. If number is zero or negative, the entire string is inserted. All characters to the right of the cursor are shifted right, with the rightmost characters on the line being lost. The cursor position does not change (after moving to origin).
