Struct SharedVmoRegisterProxy 

pub struct SharedVmoRegisterProxy { /* private fields */ }

Implementations

impl SharedVmoRegisterProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.sharedmemory/SharedVmoRegister.

pub fn take_event_stream(&self) -> SharedVmoRegisterEventStream

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

Panics

Panics if the event stream was already taken.

pub fn register_vmo( &self, vmo_id: u32, vmo: Range, rights: SharedVmoRight, ) -> QueryResponseFut<SharedVmoRegisterRegisterVmoResult, DefaultFuchsiaResourceDialect>

Registers a VMO and transfers ownership to the driver. vmo_id: The ID chosen by the client that will be used in operations on this VMO. vmo: The handle, offset, and size of this VMO. IO operations on this VMO will be relative to the offset and size specified here. rights: A bit field of SharedVmoRight values indicating how this VMO may be used. Callers should assume that the driver will map and/or pin the VMO using these rights.

pub fn unregister_vmo( &self, vmo_id: u32, ) -> QueryResponseFut<SharedVmoRegisterUnregisterVmoResult, DefaultFuchsiaResourceDialect>

Unmaps and/or unpins the VMO and returns the handle to the caller.
