Safety

Visit each owner once through unchanged pinned projections, presence, and operation authority. Admission includes every present owner’s route, without merging duplicate owners. Keep the root pinned; shutdown preserves client storage and finish destroys dependents before providers.

Required Associated Constants

const ROUTES: Routes

const COORDS: usize

Upper bound on idle coordinator probes, including delegated probes.

Provided Associated Constants

const WAKE_ROUTES: Routes = settings::Routes::EMPTY

Routes whose installed owners may receive activation.

Required Methods

fn select_park() -> Option<Self::ParkPlan>

unsafe fn park<'app, 'driver, 'turn>( app: Pin<&'app mut Self>, plan: &mut Self::ParkPlan, park: Park<'driver, 'turn, 'd>, )

where 'd: 'driver + 'turn,

Safety

The exact pinned root is installed and this plan completed preparation and admission for that root. The park authority belongs to the same root.

fn progress(app: Pin<&Self>, view: Progress<'_, '_, 'd>) -> Progress<'d>

fn stopping(app: Pin<&Self>, view: Progress<'_, '_, 'd>) -> Progress<'d>

Provided Methods

fn prepare_park(_: Pin<&Self>, _: &mut Self::ParkPlan) -> Option<Count>

Prepares the selected coordinator shares once after installation. The count does not exceed COORDS; field presence and shares remain stable through finish. None reports count overflow.

fn admit(_: Pin<&Self>, needs: &mut Needs) -> Result<(), Claim>

Accumulates the routes of the owners actually present in this pinned root.

fn released(released: Released<'_, Self>) -> Released<'_, Self>

fn install<'app, 'owner>( install: Install<'app, 'owner, 'd, Self>, ) -> Install<'app, 'owner, 'd, Self>

unsafe fn activate<'app, 'driver, 'turn>( _: Pin<&'app mut Self>, _: Activate<'driver, 'turn, 'd>, ) -> bool

where 'd: 'driver + 'turn,

Returns whether a present owner handled this activation. On false, the caller may continue through the remaining owners of the same root.

Safety

The activation retains this exact installed pinned root and a target declared by WAKE_ROUTES.

fn dispatch<'app, 'driver, 'turn>( call: Dispatch<'app, 'driver, 'turn, 'd, Self>, ) -> ControlFlow<Event<'d>>

fn shutdown<'app, 'turn, 'driver>( shutdown: Shutdown<'app, 'turn, 'driver, 'd, Self>, ) -> Shutdown<'app, 'turn, 'driver, 'd, Self>

fn finish<'app, 'finish, 'owner, 'epoch>( finish: Finish<'app, 'finish, 'owner, 'epoch, 'd, Self>, ) -> Finish<'app, 'finish, 'owner, 'epoch, 'd, Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<'app, 'd, H, T> App<'d> for Bound<'app, 'd, H, T>

where H: App<'d>, T: App<'d>,

const ROUTES: Routes

const WAKE_ROUTES: Routes

const COORDS: usize

impl<'app, 'd, H, T> App<'d> for dope_runtime::topology::lending::raw::Pair<'app, 'd, H, T>

where Owner<Pin<&'app mut H>, H>: App<'d>, Owner<ManuallyDrop<T>, T>: App<'d>,

SAFETY: each lifecycle operation visits all declared owners once, in declaration order, through the same pinned projections and presence. The root stays pinned through finish and retains each operation’s authority.

const ROUTES: Routes

const WAKE_ROUTES: Routes

const COORDS: usize

impl<'d, A, B> App<'d> for dope_runtime::client::Pair<'d, A, B>

where A: App<'d> + Root<'d>, B: App<'d> + Root<'d>,

SAFETY: each lifecycle operation visits all declared owners once, in declaration order, through the same pinned projections and presence. The root stays pinned through finish and retains each operation’s authority.
