Struct DeviceProxy

pub struct DeviceProxy { /* private fields */ }

Implementations

impl DeviceProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.i2c/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 transfer( &self, transactions: &[Transaction], ) -> QueryResponseFut<DeviceTransferResult, DefaultFuchsiaResourceDialect>

Issue one or more transactions to a particular I2C device.

Each Transaction is performed in the order in which it appears in transactions. Data for read transfers (if there are any) is returned through read_data, which has one entry for each read transfer in transactions. Transaction processing continues until all transfers have been completed, an error occurs, or the target issues a NACK in response to a write transfer.

The possible error values are: ZX_ERR_INVALID_ARGS: transactions has zero elements, data_transfer was not specified for a Transaction, or there was a zero-length DataTransfer. ZX_ERR_OUT_OF_RANGE: A DataTransfer was too large to be handled by this I2C controller. ZX_ERR_IO_NOT_PRESENT: The device did not respond to its I2C address. ZX_ERR_IO_REFUSED: The device issued a NACK before the end of a write transfer.

pub fn get_name( &self, ) -> QueryResponseFut<DeviceGetNameResult, DefaultFuchsiaResourceDialect>

Get the name of this I2C Device. Returns ZX_ERR_NOT_SUPPORTED if the name is unspecified or the empty string.

impl Proxy for DeviceProxy

type Protocol = DeviceMarker

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

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

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