Trait Implementations§

Source§

impl LifecycleHandler for NullLifecycleHandler

Source§

fn send_to_new_process<'life0, 'async_trait>( &'life0 mut self, _write_pipe: PipeWriter, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Called after the child process has been spawned, allowing the current process to send state to the child process. The child process can receive this data by calling receive_from_old_process.
Source§

fn pre_new_process<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Called before the child process has been spawned.
Source§

fn new_process_failed<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Called after send_to_new_process if the child process fails to start successfully. This gives you an opportunity to undo any state changes made in send_to_new_process.
