Crate gasm_host 

Native host for gasm games.

Load a guest .wasm with host::Game::load, drive it with host::Game::frame at the guest’s frame rate, and plug in the pieces you need: gfx::Gfx (wgpu: window, offscreen or null), audio::AudioSink (cpal), net::Net (WebSocket, ws:///wss://), storage::Storage (per-game key/value). The gasm-run binary in this crate is a complete runner built from these parts; gasm-relay is the room relay.

ABI: https://gasm.emdzej.pl/docs/abi (machine-readable: spec/abi.json).
