Enum Change

}

Something a tool lists came or went, so what it last read of it is stale. Says what to read again, not what it now reads.

root is the window a registry or a bus belongs to, as RootId::get numbers it; None for the application’s own, or for one no window owns.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ActorAdded

Fields

root: Option<u64>

id: usize

type_name: &'static str

owner: Owner

ActorRemoved

Fields

root: Option<u64>

id: usize

ActorHandled

An actor handled a message, so its state may read differently now. Where it lives is what Change::ActorAdded said.

Fields

id: usize

TimerStarted

A timer a tool may see started; its id is the one the running timers list it under.

Fields

id: u64

TimerStopped

A timer stopped, or stopped being one a tool may see.

Fields

id: u64

Subscriptions

Something subscribed to a bus, or stopped being.

Fields

bus: Bus

root: Option<u64>

RouterOpened

A window’s router navigated for the first time.

Fields

root: u64

RouterClosed

Fields

root: u64
