# `Wasmex.Components.Instance`

The component model equivalent to `Wasmex.Instance`.

Most applications should use `Wasmex.Components` or
`Wasmex.Components.ComponentServer` instead.

# `t`

```elixir
@type t() :: %Wasmex.Components.Instance{
  instance_resource: binary(),
  reference: reference(),
  store_resource: binary()
}
```

# `call_function`

```elixir
@spec call_function(
  t(),
  Wasmex.Components.function_name_or_path(),
  list(),
  GenServer.from(),
  non_neg_integer() | nil
) :: :ok
```

Schedules a call to an exported component function.

The `from` argument must be the caller tuple passed to
`c:GenServer.handle_call/3`. The result is sent to that caller after execution.
If `timeout` expires first, the component call continues to completion because
Wasmtime cannot cancel it without invalidating the instance; the late result
is discarded.

# `new`
