Macro rust_libretro::retro_core

macro_rules! retro_core {
    ( $( $definition:tt )+ ) => { ... };
}

This macro must be used to initialize your Core.

Examples

struct ExampleCore {
    option_1: bool,
    option_2: bool,

    pixels: [u8; 800 * 600 * 4],
    timer: i64,
    even: bool,
}
retro_core!(ExampleCore {
    option_1: false,
    option_2: true,

    pixels: [0; 800 * 600 * 4],
    timer: 5_000_001,
    even: true,
});
