Implementations

impl SharedDoor

pub fn resources(&self) -> Vec<ResourceSpec>

The resources the surface published when its host last published it, with their actions.

pub fn actions(&self) -> Vec<ActionDescriptor>

What the surface offered when its host last published it.

pub fn revision(&self) -> u64

Changes whenever Self::actions does.

pub fn invoke( &self, address: ActionAddress, arguments: Map<String, Value>, ) -> Rc<RefCell<Option<Result<ResourceOperationStart, DoorError>>>>

Queue address for the host. The answer is None until the host served it.

pub fn has_queued(&self) -> bool

Whether anything waits for the host.

pub fn serve(&self, app: &mut dyn AppWidget) -> bool

Host: run what was queued through app’s door, oldest first. Returns whether anything ran.

pub fn serve_with( &self, run: impl FnMut(&ActionAddress, &Map<String, Value>) -> Result<ResourceOperationStart, DoorError>, ) -> bool

Host: run what was queued through run, the surface’s own door, oldest first: for a host holding the surface as something other than an AppWidget. Returns whether anything ran.

pub fn refuse_queued(&self)

Host: refuse what was queued, for a surface that is gone.

pub fn publish(&self, app: Option<&dyn AppWidget>)

Host: publish what app offers now; nothing for a surface that is gone or offers nothing to this device.

pub fn publish_resources(&self, resources: Option<Vec<ResourceSpec>>)

Host: publish resources, what the surface offers now; None for a surface that is gone.
