Function ncursesw::copywin

pub fn copywin(
    src_handle: WINDOW, 
    dst_handle: WINDOW, 
    smin: Origin, 
    dmin: Origin, 
    dmax: Origin, 
    overlay: bool
) -> Result<(), NCurseswError>

The copywin() routine provides a finer granularity of control over the overlay() and overwrite() routines. As in the prefresh() routine, a rectangle is specified in the destination window, (dmin) and (dmax), and the upper-left-corner coordinates of the source window, (smin). If the argument overlay is true, then copying is non-destructive, as in overlay().
