Wasmex.Wasi.WasiP2Options (wasmex v0.10.0)

Configures WASI P2 support for a Wasmex.Components.Store.

WASI (WebAssembly System Interface) P2 provides system interface capabilities to WebAssembly components, allowing them to interact with the host system in a controlled manner.

Options

  • :inherit_stdin - When true, allows the component to read from standard input. Defaults to true.

  • :inherit_stdout - When true, allows the component to write to standard output. Defaults to true.

  • :inherit_stderr - When true, allows the component to write to standard error. Defaults to true.

  • :allow_http - When true, enables HTTP capabilities for the component. Defaults to false.

  • :args - List of command-line arguments to pass to the component. Defaults to [].

  • :env - Map of environment variables to make available to the component. Defaults to %{}.

Example 

iex> wasi_opts = %Wasmex.Wasi.WasiP2Options{
...>   args: ["--verbose"],
...>   env: %{"DEBUG" => "1"},
...>   allow_http: true
...> }
iex> {:ok, pid} = Wasmex.Components.start_link(%{
...>   path: "my_component.wasm",
...>   wasi: wasi_opts
...> })
