Struct FixedWindow

pub(crate) struct FixedWindow {
    recvwindow: RecvWindow<CircParams>,
    sendwindow: SendWindow<CircParams>,
    params: FixedWindowParams,
}

Fixed window algorithm which is essentially the SENDME v0 with fixed receive and send window size.

Fields

recvwindow: RecvWindow<CircParams>

Window used to say how many cells we can receive.

sendwindow: SendWindow<CircParams>

Window used to say how many cells we can send.

params: FixedWindowParams

The params from the consensus.

Implementations

impl FixedWindow

pub(crate) fn new(params: FixedWindowParams) -> Self

Create a new FixedWindow form a given initial sendwindow size.

Note: the initial recvwindow size is given by sendme::CircParams::start.

Trait Implementations

impl Clone for FixedWindow

fn clone(&self) -> FixedWindow

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CongestionControlAlgorithm for FixedWindow

fn uses_stream_sendme(&self) -> bool

Return true iff this algorithm uses stream level SENDMEs.

fn is_next_cell_sendme(&self) -> bool

Return true iff the next cell is expected to be a SENDME.

fn can_send(&self) -> bool

Return true iff a cell can be sent on the wire according to the congestion control algorithm.

fn cwnd(&self) -> Option<&CongestionWindow>

Return the congestion window object. The reason is returns an Option is because not all algorithm uses one and so we avoid acting on it if so.

fn sendme_received( &mut self, _state: &mut State, _rtt: &mut RoundtripTimeEstimator, _signals: CongestionSignals, ) -> Result<()>

Inform the algorithm that we’ve just received a SENDME.

fn sendme_sent(&mut self) -> Result<()>

Inform the algorithm that we just sent a SENDME.

fn data_received(&mut self) -> Result<bool>

Inform the algorithm that we just got a DATA cell.

fn data_sent(&mut self) -> Result<()>

Inform the algorithm that we just sent a DATA cell.

fn inflight(&self) -> Option<u32>

Available on crate feature conflux only.

Return the number of in-flight cells (sent but awaiting SENDME ack).

fn algorithm(&self) -> Algorithm

Return the congestion control Algorithm implemented by this type.

impl Debug for FixedWindow

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
