Function libnotcurses_sys::ncplane_set_fg_rgb8

pub unsafe extern "C" fn ncplane_set_fg_rgb8(
    n: *mut ncplane, 
    r: c_uint, 
    g: c_uint, 
    b: c_uint
) -> c_int

Set the current fore/background color using RGB specifications. If the terminal does not support directly-specified 3x8b cells (24-bit “TrueColor”, indicated by the “RGB” terminfo capability), the provided values will be interpreted in some lossy fashion. None of r, g, or b may exceed 255. “HP-like” terminals require setting foreground and background at the same time using “color pairs”; Notcurses will manage color pairs transparently.
