Type Alias libnotcurses_sys::NcFadeCb

pub type NcFadeCb = Option<unsafe extern "C" fn(_: *mut Nc, _: *mut NcPlane, _: *const NcTime, _: *mut c_void) -> NcResult_i32>;

Called for each fade iteration on a fading NcPlane.

If anything but 0 is returned, the fading operation ceases immediately, and that value is propagated out.

The recommended absolute display time target is passed in ‘tspec’.
