Struct MapProjectionHandle 

pub struct MapProjectionHandle { /* private fields */ }

Standalone projection snapshot created from a map transform.

The projection does not retain the source map after creation. It remains thread-affine and must be used and closed on its owner thread.

Implementations

impl MapProjectionHandle

pub fn close(self) -> Result<(), HandleOperationError<Self>>

Explicitly destroys the projection snapshot.

pub fn camera(&self) -> Result<CameraOptions>

Reads the projection helper’s current camera snapshot.

pub fn set_camera(&self, camera: &CameraOptions) -> Result<()>

Applies camera fields to this projection helper.

pub fn set_visible_coordinates( &self, coordinates: &[LatLng], padding: EdgeInsets, ) -> Result<()>

Updates the projection camera so coordinates are visible within padding.

pub fn set_visible_geometry( &self, geometry: &Geometry, padding: EdgeInsets, ) -> Result<()>

Updates the projection camera so geometry coordinates are visible.

pub fn pixel_for_lat_lng(&self, coordinate: LatLng) -> Result<ScreenPoint>

Converts a geographic world coordinate to a screen point.

pub fn lat_lng_for_pixel(&self, point: ScreenPoint) -> Result<LatLng>

Converts a screen point to a geographic world coordinate.
