Implementations§
source§impl ReaderSynchronousProxy
impl ReaderSynchronousProxy
pub fn new(channel: Channel) -> Self
pub fn into_channel(self) -> Channel
sourcepub fn wait_for_event(&self, deadline: Time) -> Result<ReaderEvent, Error>
pub fn wait_for_event(&self, deadline: Time) -> Result<ReaderEvent, Error>
Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.
sourcepub fn get_elements(
&self,
___deadline: Time
) -> Result<ReaderGetElementsResult, Error>
pub fn get_elements( &self, ___deadline: Time ) -> Result<ReaderGetElementsResult, Error>
Returns a vector of supported processing elements.
Must return one or more processing elements, or ZX_ERR_NOT_SUPPORTED
.
sourcepub fn watch_element_state(
&self,
processing_element_id: u64,
___deadline: Time
) -> Result<ElementState, Error>
pub fn watch_element_state( &self, processing_element_id: u64, ___deadline: Time ) -> Result<ElementState, Error>
Get the processing element state via a hanging get. For a given processing_element_id
,
the driver will reply to the first WatchElementState
sent by the client.
The driver will not respond to subsequent client WatchElementState
calls for a
given processing_element_id
until any field of the Element
table
changes from what was most recently reported for that processing_element_id
.
The driver will close the protocol channel with an error of ZX_ERR_BAD_STATE
, if this
method is called again while there is already a pending WatchElementState
for this client
and processing_element_id.
sourcepub fn get_topologies(
&self,
___deadline: Time
) -> Result<ReaderGetTopologiesResult, Error>
pub fn get_topologies( &self, ___deadline: Time ) -> Result<ReaderGetTopologiesResult, Error>
Returns a vector of supported topologies.
Must return one or more topologies, or ZX_ERR_NOT_SUPPORTED
.
If more than one topology is returned, then the client may choose any of the topologies from
the list with SetTopology
.
If only one topology is returned, then the topology definition is informational only since
the one and only topology used can’t be changed with SetTopology
.
If GetElements
returns one or more elements, GetTopologies
must return one or
more topologies.
sourcepub fn watch_topology(&self, ___deadline: Time) -> Result<u64, Error>
pub fn watch_topology(&self, ___deadline: Time) -> Result<u64, Error>
Get the current topology via a hanging get.
The driver will immediately reply to the first WatchTopology
sent by each client. The
driver will not respond to subsequent WatchTopology
calls from that client until the
signal-processing topology changes, which occurs as a result of a SetTopology
call.
The driver will close the protocol channel with an error of ZX_ERR_BAD_STATE
, if this
method is called again while there is already a pending WatchTopology
for this client.
