Functions

call_function(instance, function_or_path, args, from, timeout \\ nil)

@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 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.
