Struct DeviceProxy 

pub struct DeviceProxy { /* private fields */ }

Implementations

impl DeviceProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.spi/Device.

pub fn take_event_stream(&self) -> DeviceEventStream

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

Panics

Panics if the event stream was already taken.

pub fn transmit( &self, buffer: &SharedVmoBuffer, ) -> QueryResponseFut<SharedVmoIoTransmitResult, DefaultFuchsiaResourceDialect>

Sends the data in buffer to the device.

pub fn receive( &self, buffer: &SharedVmoBuffer, ) -> QueryResponseFut<SharedVmoIoReceiveResult, DefaultFuchsiaResourceDialect>

Receives data from the device into buffer.

pub fn exchange( &self, tx_buffer: &SharedVmoBuffer, rx_buffer: &SharedVmoBuffer, ) -> QueryResponseFut<SharedVmoIoExchangeResult, DefaultFuchsiaResourceDialect>

Simultaneously transmits and receives data. The size fields of tx_buffer and rx_buffer must be the same.

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.

pub fn transmit_vector( &self, data: &[u8], ) -> QueryResponseFut<i32, DefaultFuchsiaResourceDialect>

Half-duplex transmit data to a SPI device; always transmits the entire buffer on success.

pub fn receive_vector( &self, size: u32, ) -> QueryResponseFut<(i32, Vec<u8>), DefaultFuchsiaResourceDialect>

Half-duplex receive data from a SPI device; always reads the full size requested.

pub fn exchange_vector( &self, txdata: &[u8], ) -> QueryResponseFut<(i32, Vec<u8>), DefaultFuchsiaResourceDialect>

Full-duplex SPI transaction. Received data will exactly equal the length of the transmit buffer.

pub fn can_assert_cs( &self, ) -> QueryResponseFut<bool, DefaultFuchsiaResourceDialect>

Returns true if the device can call |AssertCs()| and |DeassertCs()|.

pub fn assert_cs(&self) -> QueryResponseFut<i32, DefaultFuchsiaResourceDialect>

Assert CS for this device. Returns ZX_ERR_NOT_SUPPORTED if there is more than one device on the bus.

pub fn deassert_cs( &self, ) -> QueryResponseFut<i32, DefaultFuchsiaResourceDialect>

Deassert CS for this device. Returns ZX_ERR_BAD_STATE if CS is already deasserted. Returns ZX_ERR_NOT_SUPPORTED if there is more than one device on the bus.
