Expand description

A command to execute at the end of Reactor::run_once.

Variants§

§

RunCmd

Run a single CircuitCmd command.

Fields

§leg: UniqId

The unique identifier of the circuit leg to run the command on

§cmd: CircuitCmd

The command to run.

§

HandleControl(CtrlMsg)

Handle a control message

§

HandleCell

Handle an input message.

Fields

§leg: UniqId

The unique identifier of the circuit leg the message was received on.

§cell: ClientCircChanMsg

The message to handle.

§

RemoveLeg

Remove the specified circuit leg from the conflux set.

Returned whenever a single circuit leg needs to be be removed from the reactor’s conflux set, without necessarily tearing down the whole set or shutting down the reactor.

Note: this event can cause the reactor to shut down (and the conflux set to be closed).

See the ConfluxSet::remove docs for more on the exact behavior of this command.

Fields

§leg: UniqId

The leg to remove.

§reason: RemoveLegReason

The reason for removal.

This is only used for conflux circuits that get removed before the conflux handshake is complete.

The RemoveLegReason is mapped by the reactor to a ConfluxHandshakeError that is sent to the initiator of the handshake to indicate the reason the handshake failed.

§

PaddingAction

Take some event (blocking or unblocking a circuit, or sending padding) based on the circuit padding backend code.

Fields

§leg: UniqId

The leg on which to take the padding event .

§padding_event: PaddingEvent

The event to take.

§

ProtoViolation

Protocol violation. This leads for now to the close of the circuit reactor. The error causing the violation is set in err.

Fields

§err: Error

The error that causes this protocol violation.

Implementations§

Source§

impl CircuitEvent

Source

fn order_within_batch(&self) -> u8

Return the ordering with which we should handle this event within a list of events returned by a single call to next_circ_event().

NOTE: Please do not make this any more complicated: It is a consequence of a kludge that we need this sorting at all. Assuming that eventually, we switch away from the current poll-oriented next_circ_event design, we may be able to get rid of this entirely.
