Struct CommonSynchronousProxy

pub struct CommonSynchronousProxy { /* private fields */ }

Implementations

impl CommonSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<CommonEvent, 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 query( &self, ___deadline: MonotonicInstant, ) -> Result<(BlockInfo, u64), Error>

Obtains the parameters of the block device (block_info_t) and the required size of block_txn_t. The block_txn_ts submitted via Queue() must have block_op_size_out - sizeof(block_op_t) bytes available at the end of the structure for the use of the driver.

pub fn queue( &self, txn: BlockOp, ___deadline: MonotonicInstant, ) -> Result<(i32, BlockOp), Error>

Submits an I/O request for processing. Ownership of op is transferred to callee until completion_cb is invoked. Success or failure will be reported via the completion_cb. This callback may be called before the Queue() method returns.

impl SynchronousProxy for CommonSynchronousProxy

type Proxy = CommonProxy

The async proxy for the same protocol.

type Protocol = CommonMarker

The protocol which this Proxy controls.

fn from_channel(inner: Channel) -> Self

Create a proxy over the given channel.
