Struct DeviceSynchronousProxy

pub struct DeviceSynchronousProxy { /* private fields */ }

Implementations

impl DeviceSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DeviceEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn transfer( &self, transactions: &[Transaction], ___deadline: MonotonicInstant, ) -> Result<DeviceTransferResult, Error>

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, ___deadline: MonotonicInstant, ) -> Result<DeviceGetNameResult, Error>

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