[−][src]Trait hydrogen::Handler
Events reported to lib consumer.
Required methods
fn on_server_created(&mut self, fd: RawFd)
This method is called once the listening RawFd has been created.
It should be used to set/remove any flags on the underlying RawFd before listen
is
called on the fd.
fn on_new_connection(&mut self, fd: RawFd) -> Arc<UnsafeCell<dyn Stream>>
This method is called whenever accept
returns a new TCP connection.
The returned trait object is added to the connection pool and the epoll interest list.
fn on_data_received(&mut self, socket: HydrogenSocket, buf: Vec<u8>)
This method is called whenever the recv
call returns an Ok(_) result.
fn on_connection_removed(&mut self, fd: RawFd, err: Error)
This method is called after a stream has been removed from the connection poll and epoll
interest list, with the std::io::Error
as the reason removed.
At the time of this call, the underlying fd has been shutdown and closed. No system level shutdown is needed, only application level cleanup.
