Expand description

event handler for connection object

Required Associated Types§

Source

type InitialData: Clone

initial data provided to new

Source

type ConstructError

error type raised from new

Required Methods§

Source

fn new( init_data: Self::InitialData, connection: &mut Connection<Self>, ) -> Result<Self, Self::ConstructError>

construct handler object

Provided Methods§

Source

fn handshake_done(&mut self, _connection: &mut Connection<Self>)

called on handshake finish (or incomplete handshake)

Source

fn data_received( &mut self, _connection: &mut Connection<Self>, _direction: Direction, )

called on data received

Source

fn ack_received( &mut self, _connection: &mut Connection<Self>, _direction: Direction, )

called when data is acked, direction is of the ack packet, not the stream

Source

fn fin_received( &mut self, _connection: &mut Connection<Self>, _direction: Direction, )

called on FIN

Source

fn rst_received( &mut self, _connection: &mut Connection<Self>, _direction: Direction, _extra: PacketExtra, )

called on RST

Source

fn stream_end( &mut self, _connection: &mut Connection<Self>, _direction: Direction, )

ACK for FIN received for stream

Source

fn connection_desync( &mut self, _connection: &mut Connection<Self>, _direction: Direction, )

connection fatally desynchronized, direction is our best guess for the direction of the packet which caused the desync

Source

fn will_retire(&mut self, _connection: &mut Connection<Self>)

called when the connection is removed from the hashtable

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
