Expand description

Trait implemented by a Rust libretro core.

Required methods describe metadata, AV timing, and per-frame execution. Optional methods cover setup, content loading, savestates, disk control, hardware-render lifecycle, netpacket callbacks, and other libretro surfaces. Export an implementation with export_core!.
