Module maybenot_padding 

A maybenot-specific backend for padding.

Modules

backend 🔒

Padding backend based on maybenot.

Structs

BlockingState 🔒

Current padding-related blocking status for a circuit.

CircuitPadder

A opaque handle to a padding implementation for a single hop.

CircuitPadderConfig

Builder for PaddingRules.

PaddingController 🔒

A handle to the padding state of a single circuit.

PaddingEventStream 🔒

A stream of PaddingEvent to tell a circuit when (if at all) it should send padding and block traffic.

PaddingRules 🔒

Specifications for a set of maybenot padding machines as used in Arti: used to construct a maybenot::Framework.

PaddingShared 🔒

The shared state for a single circuit’s padding.

PaddingStats 🔒

The number of padding and non-padding cells we have received from each hop, and the rules for how many are allowed.

QueuedCellPaddingInfo 🔒

Information about a queued cell that we need to feed back into the padding subsystem.

SendPadding 🔒

An indication that we should send a padding cell.

StartBlocking 🔒

An instruction to start blocking traffic or to change the rules for blocking traffic.

Enums

Bypass 🔒

Whether a piece of padding can bypass a bypassable case of blocking.

CircuitPadderConfigError

An error returned from validating a CircuitPadderConfig.

PaddingEvent 🔒

An instruction from the padding machine to the circuit.

PerHopPaddingEvent 🔒

An instruction from a single padding hop.

Replace 🔒

Whether a given piece of padding can be replaced with queued data.

Constants

MAX_HOPS 🔒

Absolute upper bound for number of hops.

Functions

hopnum_from_hop_idx 🔒

Construct a HopNum from an index into the hops field of a PaddingShared.

new_padding 🔒

Create a new, empty padding instance for a new circuit.

Type Aliases

Duration 🔒

The type of Duration that we’ll use for our padding machines.

Instant 🔒

The type of Instant that we’ll use for our padding machines.

PaddingEventQueue 🔒

A type we use to generate a set of PaddingEvent.

PerHopPaddingEventVec 🔒

A type we use to generate a set of PaddingEvent.
