Expand description

:wasm guest — runtime + component + WASI contract.

Fields§

§runtime: WasmRuntime

Which WASM runtime will host this guest.

§wasi_preview: WasiPreview

WASI version.

§component: BuildRef

The component artifact — a WASM/WAT/Component Model blob produced by a Nix derivation.

§features: WasmFeatures

AOT/JIT/SIMD/wasi-http/wasi-nn toggles.

§capabilities: WasmCapabilities

What the host grants this guest — stdio, env, argv, preopens, and the non-WASI host imports the embedder supplies.

Defaults to deny-all, which is a deliberate posture change. The engines used to hardcode their own grant (wasmtime handed every guest stdout+stderr; wasmi and wasmer handed out nothing), so the capability surface was whichever impl you happened to land on. Declaring it here makes it a property of the guest instead of the backend.
