This package contains the runtime for executing Wasm wrappers.
Quickstart
The following code snippet demonstrates how to use the runtime to execute a Wasm wrapper.
Imports
>>> import os >>> from typing import cast >>> from polywrap_core import Uri, FileReader, InvokerClient >>> from polywrap_wasm import WasmWrapper >>> from polywrap_msgpack import msgpack_decode >>> from polywrap_manifest import deserialize_wrap_manifest, AnyWrapManifest
Create a Wasm wrapper
>>> path_to_wrapper = os.path.join(os.path.dirname(__file__), "..", "tests", "cases", "simple") >>> assert os.path.exists(path_to_wrapper) >>> with open(os.path.join(path_to_wrapper, "wrap.wasm"), "rb") as f: ... wasm_module = f.read() >>> assert isinstance(wasm_module, bytes) >>> with open(os.path.join(path_to_wrapper, "wrap.info"), "rb") as f: ... manifest = deserialize_wrap_manifest(f.read()) >>> assert isinstance(manifest, AnyWrapManifest) >>> wrapper = WasmWrapper( ... cast(FileReader, NotImplemented), ... wasm_module, ... manifest ... ) >>> assert isinstance(wrapper, WasmWrapper)
Invocation
>>> message = "Hello, World!"
>>> args = {"arg": message}
>>> result = wrapper.invoke(
... uri=Uri.from_str("wrap://authority/path"),
... method="simpleMethod",
... args=args,
... client=cast(InvokerClient, NotImplemented),
... )
>>> assert result.encoded is True
>>> assert msgpack_decode(cast(bytes, result.result)) == message
