Struct libnotcurses_sys::ffi::ncpalette

#[repr(C)]
pub struct ncpalette {
    pub chans: [u32; 256],
}

Palette API. Some terminals only support 256 colors, but allow the full palette to be specified with arbitrary RGB colors. In all cases, it’s more performant to use indexed colors, since it’s much less data to write to the terminal. If you can limit yourself to 256 colors, that’s probably best.

Fields

chans: [u32; 256]

RGB values as regular ol’ channels
