Struct Transform 

pub struct Transform { /* private fields */ }

A reusable coordinate transformation between two CRS.

Implementations

impl Transform

pub fn new(from_crs: &str, to_crs: &str) -> Result<Self>

Create a transform from authority code strings (e.g., "EPSG:4326").

pub fn with_selection_options( from_crs: &str, to_crs: &str, options: SelectionOptions, ) -> Result<Self>

Create a transform with explicit selection options.

pub fn from_operation( operation_id: CoordinateOperationId, from_crs: &str, to_crs: &str, ) -> Result<Self>

Create a transform from an explicit registry operation id.

pub fn from_epsg(from: u32, to: u32) -> Result<Self>

Create a transform from EPSG codes directly.

pub fn from_crs_defs(from: &CrsDef, to: &CrsDef) -> Result<Self>

Create a transform from explicit CRS definitions.

pub fn convert<T: Transformable>(&self, coord: T) -> Result<T>

Transform a single coordinate.

pub fn convert_3d<T: Transformable3D>(&self, coord: T) -> Result<T>

Transform a single 3D coordinate.

pub fn source_crs(&self) -> &CrsDef

Return the source CRS definition for this transform.

pub fn target_crs(&self) -> &CrsDef

Return the target CRS definition for this transform.

pub fn selected_operation(&self) -> &CoordinateOperationMetadata

Return metadata for the selected coordinate operation.

pub fn selection_diagnostics(&self) -> &OperationSelectionDiagnostics

Return selection diagnostics for this transform.

pub fn inverse(&self) -> Result<Self>

Build the inverse transform by swapping the source and target CRS.

pub fn transform_bounds( &self, bounds: Bounds, densify_points: usize, ) -> Result<Bounds>

Reproject a 2D bounding box by sampling its perimeter.

pub fn convert_batch<T: Transformable + Clone>( &self, coords: &[T], ) -> Result<Vec<T>>

Batch transform (sequential).

pub fn convert_batch_3d<T: Transformable3D + Clone>( &self, coords: &[T], ) -> Result<Vec<T>>

Batch transform of 3D coordinates (sequential).

pub fn convert_batch_parallel<T: Transformable + Send + Sync + Clone>( &self, coords: &[T], ) -> Result<Vec<T>>

Batch transform with Rayon parallelism.

pub fn convert_batch_parallel_3d<T: Transformable3D + Send + Sync + Clone>( &self, coords: &[T], ) -> Result<Vec<T>>

Batch transform of 3D coordinates with adaptive Rayon parallelism.
