Struct InboxInstall 

pub struct InboxInstall {
    pub budget: Arc<ConnectionInboxBudget>,
    pub depth_cap: usize,
    pub notifier: Option<InboxNotifier>,
}

Everything a server connection installs onto a subscription’s inbox.

Carries the shared §5 byte budget, the per-inbox fairness cap, and the R3 wake notifier. Passed INTO the subscribe call so the installation happens at inbox construction — strictly BEFORE the registration is published to the channel actor — closing the pre-install window in which envelopes could be admitted uncharged or without a wake.

Fields

budget: Arc<ConnectionInboxBudget>

Shared per-connection byte budget (§5).

depth_cap: usize

Per-inbox envelope-count fairness trip (§5).

notifier: Option<InboxNotifier>

R3 wake notifier fired on the inbox’s empty→non-empty transition. None when the caller has no waker (scheduler-free unit tests).
