Struct WasmSandbox

Source

pub struct WasmSandbox { /* private fields */ }

Expand description

The wasmtime-backed sandbox.

Clone-cheap: the engine and linker template are shared via Arc. Each load_module yields a fresh WasmInstance with its own Store, linear memory, and empty capability envelope.

Implementations§

Source §

impl WasmSandbox

Source

pub fn new() -> Result<Self>

Construct a new sandbox with the default config (no WASI, no filesystem, no network other than what host imports provide).

Source

pub fn with_engine(engine: Engine) -> Result<Self>

Construct with a caller-supplied engine (advanced use: shared cache, custom config).

Source

pub fn engine(&self) -> &Engine

Access the underlying wasmtime engine.
