    // Required methods
    fn register_in_linker(

    fn get_wasi_state<'s>(
        instance: &'s mut <WB as WasmBackend>::Instance
    ) -> Box<dyn WasiState + 's>;
}

A type that provides WASI functionality to the given Wasm backend.

Required Methods

fn register_in_linker( store: &mut <WB as WasmBackend>::ContextMut<'_>, linker: &mut <WB as WasmBackend>::Imports, config: WasiParameters ) -> Result<(), WasiError>

Configures WASI state and adds WASI functions to the imports object.

Errors:

Returns an error if failed to open a open a directory/file.

fn get_wasi_state<'s>( instance: &'s mut <WB as WasmBackend>::Instance ) -> Box<dyn WasiState + 's>

Optional API for getting current WASI state. Returns None if not supported by current backend.

Object Safety

This trait is not object safe.
