dispatch_event(manager, callback_name, args, required_arity, initial_acc, result_handler)

Generic dispatcher that reduces over plugins and calls a specific handler function.

extract_plugin_state(plugin)

Extracts plugin state from a plugin struct.

handle_plugin_event(plugin, callback_name, args, required_arity, acc, result_handler)

Handles calling a specific callback on a plugin and processing the result.

log_plugin_error(plugin, callback_name, reason)

Logs an error from a plugin.

log_unexpected_result(plugin, callback_name, result)

Logs an unexpected result from a plugin.

update_manager_plugin(manager, old_plugin, updated_plugin)

Updates a plugin instance in the manager.

update_manager_state(manager, plugin, new_plugin_state)

Updates the manager state with a new plugin state.
