Struct ServiceBindingScope 

pub struct ServiceBindingScope { /* private fields */ }

Registration scope passed to a driver’s bind callback for a discovered FIDL service instance.

Devices registered through Self::add_scoped_device and cleanup callbacks registered via Self::on_disconnect are tied to the lifetime of the service instance and any channel passed to Self::monitor_channel (later calls overwrite any previously monitored channel). When a monitored channel observes ZX_CHANNEL_PEER_CLOSED, or when the service instance directory entry is removed or replaced in /svc/<S::SERVICE_NAME>, the watcher runs all registered teardown hooks and device removals in reverse registration order on the kernel’s main async executor.

Implementations

impl ServiceBindingScope

pub fn monitor_channel<P: SynchronousProxy + Send + Sync + 'static>( &mut self, proxy: Arc<P>, )

Retains proxy for the duration of the binding and monitors its underlying Zircon channel for ZX_CHANNEL_PEER_CLOSED, running all registered teardown hooks when the remote peer closes its endpoint.

pub fn on_disconnect( &mut self, hook: impl FnOnce(&CurrentTask) + Send + 'static, )

Registers hook to be invoked on the kernel’s main async executor with KernelThreads::system_task when the binding disconnects, executing in reverse registration order relative to other hooks and scoped devices.

pub fn add_scoped_device(&mut self, device: Device) -> Device

Registers a disconnect hook that removes device via DeviceRegistry::remove_device when the binding disconnects, returning device.

Trait Implementations

impl Debug for ServiceBindingScope

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for ServiceBindingScope

fn default() -> Self

Returns the “default value” for a type.
