Enum Direction 

pub(crate) enum Direction {
    Uplink,
    Downlink,
}

Which leg of the proxy a shaped unit is travelling on.

Two variants rather than ProxySide’s four. A unit is charged on the side it arrived on, and the two egress sides never reach a shaping decision at all — ShapeProfile::try_new rejects a rule keyed on one — but both halves of a leg answer the same question anyway, so the conversion below is total and no call site has an impossible arm to invent a value for.

Variants

Uplink

Client → relay: what the client publishes and asks for.

Downlink

Relay → client: what the client is subscribed to.

Implementations

impl Direction

fn index(self) -> usize

This leg’s row in ShapeRecorder’s session totals.

An index rather than a match at each writer: the totals are an array precisely so that charging one is the same single fetch_add at a known offset the class rows already are.
