Struct BinderProxy 

pub struct BinderProxy { /* private fields */ }

Implementations

impl BinderProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.starnix.binder/Binder.

pub fn take_event_stream(&self) -> BinderEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn set_vmo(&self, vmo: Vmo, mapped_address: u64) -> Result<(), Error>

Set the VMO to used as a share resource between the driver and the client. mapped_address is the address where the vmo is mapped in the client address space.

The driver handles the other requests of the client concurrently, so it can handle an ioctl before the VMO is mapped. Clients should use MapVmo instead.

pub fn map_vmo( &self, vmo: Vmo, mapped_address: u64, ) -> QueryResponseFut<BinderMapVmoResult, DefaultFuchsiaResourceDialect>

Maps the VMO used as a shared resource between the driver and the client. mapped_address is the address where the VMO is mapped in the client address space.

Responds once the VMO is mapped. The driver handles the other requests of the client concurrently, so the client must wait for the response before sending any ioctl that needs the VMO.

pub fn ioctl( &self, tid: u64, request: u32, arg: u64, vmo: Vmo, ioctl_reads: &[IoctlReadWrite], files: Vec<FileHandle>, ) -> QueryResponseFut<BinderIoctlResult, DefaultFuchsiaResourceDialect>

Processes a Binder ioctl. This message returns writes for the calling thread that must be processed to correctly handle the ioctl.

pub fn register_thread_channel( &self, server_end: ServerEnd<BinderThreadMarker>, ) -> QueryResponseFut<BinderRegisterThreadChannelResult, DefaultFuchsiaResourceDialect>

Registers a dedicated 1:1 channel for synchronous Binder transactions.

fn into_client_end(self) -> Result<ClientEnd<Self::Protocol>, Self>

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, NullableHandle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
