Struct RectangleTracker 

pub struct RectangleTracker { /* private fields */ }

Available on crate feature tracking only.

Tracks a known rectangle observation across a sequence of frames.

Implementations

impl RectangleTracker

pub fn new( image_path: impl AsRef<Path>, rect_observation: &RectangleObservation, ) -> Result<Self, VisionError>

Create a new rectangle tracker seeded from image_path and the known rectangle observation for that frame.

Errors

Returns VisionError if the image path is invalid, the image fails to load, or Vision rejects the tracking request.

pub fn track( &mut self, image_path: impl AsRef<Path>, ) -> Result<RectangleObservation, VisionError>

Track the rectangle into image_path and return the updated rectangle observation.

Errors

Returns VisionError if the image path is invalid, the image fails to load, or Vision rejects the tracking request.

Trait Implementations

impl Drop for RectangleTracker

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
