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 get_operating_point_info( &self, opp: u32, ___deadline: MonotonicInstant, ) -> Result<DeviceGetOperatingPointInfoResult, Error>

Returns information about a given operating point for this performance domain.

pub fn get_current_operating_point( &self, ___deadline: MonotonicInstant, ) -> Result<u32, Error>

Gets the current operating point of the device.

pub fn set_current_operating_point( &self, requested_opp: u32, ___deadline: MonotonicInstant, ) -> Result<DeviceSetCurrentOperatingPointResult, Error>

Set the operating point of this device to the requested operating point. Returns ZX_OK, if the device is in a working state and the operating point is changed to requested_opp successfully. out_opp will be same as requested_opp. Returns error status, if switching to the requested_opp was unsuccessful. out_opp is the operating performance point (OPP) that the device is currently in.

pub fn get_operating_point_count( &self, ___deadline: MonotonicInstant, ) -> Result<DeviceGetOperatingPointCountResult, Error>

Returns the number of operating points within this performance domain.

pub fn get_num_logical_cores( &self, ___deadline: MonotonicInstant, ) -> Result<u64, Error>

Returns the number of logical cores contained within this performance domain.

pub fn get_logical_core_id( &self, index: u64, ___deadline: MonotonicInstant, ) -> Result<u64, Error>

Returns a global system-wide core ID for the nth core in this performance domain. index must be a value in the range [0, n) where n is the value returned by GetNumLogicalCores().

pub fn get_domain_id(&self, ___deadline: MonotonicInstant) -> Result<u32, Error>

Returns the id of this performance domain within its package. This number should be stable across boots, but clients should prefer to use GetRelativePerformance to differentiate cores if possible.

pub fn get_relative_performance( &self, ___deadline: MonotonicInstant, ) -> Result<DeviceGetRelativePerformanceResult, Error>

The relative performance of this domain as configured by the platform, if known. The highest performance domain should return 255, while others should return N/255 fractional values relative to that domain. Returns ZX_ERR_NOT_SUPPORTED if the performance level is unknown.

Trait Implementations

impl Debug for DeviceSynchronousProxy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl SynchronousProxy for DeviceSynchronousProxy

type Proxy = DeviceProxy

The async proxy for the same protocol.

type Protocol = DeviceMarker

The protocol which this Proxy controls.

fn from_channel(inner: Channel) -> Self

Create a proxy over the given channel.

fn into_channel(self) -> Channel

Convert the proxy back into a channel.

fn as_channel(&self) -> &Channel

Get a reference to the proxy’s underlying channel.

fn is_closed(&self) -> Result<bool, Status>

Returns true if the proxy has received the PEER_CLOSED signal.
