Struct SensorDescriptor 

#[repr(C)]
pub struct SensorDescriptor {
    pub sensor_type: SensorType,
    pub device_id: u64,
    pub filter_hash: u64,
    pub sample_rate: u32,
}

Sensor descriptor identifying a data source.

Used in sensor_subscribe to specify which sensor to monitor.

Fields

sensor_type: SensorType

Type of sensor.

device_id: u64

Device identifier (hardware address, URL hash, stream ID, etc.). Interpretation depends on sensor_type.

filter_hash: u64

Filter expression hash (0 = no filter). The actual filter is stored in a region and referenced by hash.

sample_rate: u32

Requested sampling rate (events per second). 0 = all events (no downsampling).

Implementations

impl SensorDescriptor

pub const fn new(sensor_type: SensorType, device_id: u64) -> Self

Creates a new sensor descriptor.

pub const fn with_sample_rate(self, rate: u32) -> Self

Creates a descriptor with sampling rate.

pub const fn with_filter(self, filter_hash: u64) -> Self

Creates a descriptor with a filter.

pub const fn is_downsampled(&self) -> bool

Returns true if downsampling is enabled.

pub const fn has_filter(&self) -> bool

Returns true if a filter is applied.

Trait Implementations

impl Clone for SensorDescriptor

fn clone(&self) -> SensorDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SensorDescriptor

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

Formats the value using the given formatter.

impl Default for SensorDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SensorDescriptor

fn eq(&self, other: &SensorDescriptor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
