Struct Watching 

Source 
struct Watching {
    subjects: Vec<Subject>,
    showing: Option<SessionSlot>,
    showing_attached: bool,
}
Expand description

What this connection is watching, and which of it is on screen.

The two travel together because only a subject this connection watches can reach it, and only a seat can be shown. They mean different things: the subscription carries a seat’s frames, and the showing is what spends its marks.

Fields§

§subjects: Vec<Subject>§showing: Option<SessionSlot>§showing_attached: bool

Whether the connection holds the showing’s attach on Live.

The two halves can arrive in either order. Both clients subscribe first on a resume, but the route effect that sends showing races the page’s mount, so a showing can still land before its subscribe. A mark is spent only when the pair is complete: the showing that lands first is remembered and the subscribe that completes it spends - never both, or the count would be two.
