Enum TrackState 

#[repr(u32)]
pub enum TrackState {
    Lost = 0,
    Inferred = 1,
    Known = 2,
}

This is the tracking state of a sensory input in the world, like a controller’s position sensor, or a QR code identified by a tracking system. https://stereokit.net/Pages/StereoKit/TrackState.html

Examples

use stereokit_rust::system::{TrackState, Input, Handed};

let controller = Input::controller(Handed::Right);

assert_eq!(controller.tracked_pos, TrackState::Lost);
assert_ne!(controller.tracked_pos, TrackState::Inferred);
assert_ne!(controller.tracked_pos, TrackState::Known);

assert_eq!(controller.tracked_rot, TrackState::Lost);
assert_ne!(controller.tracked_rot, TrackState::Inferred);
assert_ne!(controller.tracked_rot, TrackState::Known);

Variants

Lost = 0

The system has no current knowledge about the state of this input. It may be out of visibility, or possibly just disconnected.

Inferred = 1

The system doesn’t know for sure where this is, but it has an educated guess that may be inferred from previous data at a lower quality. For example, a controller may still have accelerometer data after going out of view, which can still be accurate for a short time after losing optical tracking.

Known = 2

The system actively knows where this input is. Within the constraints of the relevant hardware’s capabilities, this is as accurate as it gets!

Trait Implementations

impl Clone for TrackState

fn clone(&self) -> TrackState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrackState

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

Formats the value using the given formatter.

impl PartialEq for TrackState

fn eq(&self, other: &TrackState) -> 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.
