Struct BnHostProxy

pub struct BnHostProxy(/* private fields */);

A binder Remotable that holds an IHostProxy object.

Implementations

impl BnHostProxy

pub fn new_binder<T: IHostProxy + Sync + Send + 'static>( inner: T, features: BinderFeatures, ) -> Strong<dyn IHostProxy>

Create a new binder service.

pub fn downcast_binder<T: IHostProxy>(&self) -> Option<&T>

Tries to downcast the interface to another type. When receiving this object from a binder call, make sure that the object received is a binder native object and that is of the right type for the Downcast:

let binder = received_object.as_binder(); if !binder.is_remote() { let binder_native: Binder = binder.try_into()?; let original_object = binder_native.downcast_binder::(); // Check that returned type is not None before using it }

Handle the error cases instead of just calling unwrap or expect to prevent a malicious caller to mount a Denial of Service attack.

impl BnHostProxy

pub fn new_async_binder<T, R>( inner: T, rt: R, features: BinderFeatures, ) -> Strong<dyn IHostProxy>

where T: IHostProxyAsyncServer + Interface + Send + Sync + 'static, R: BinderAsyncRuntime + Send + Sync + 'static,

Create a new async binder service.

pub fn try_into_local_async<P: BinderAsyncPool + 'static>( _native: Binder<Self>, ) -> Option<Strong<dyn IHostProxyAsync<P>>>
