Struct Transformer 

pub struct Transformer { /* private fields */ }

Coordinate transformer that handles transformations between CRS.

Implementations

impl Transformer

pub fn new(source_crs: Crs, target_crs: Crs) -> Result<Self>

Creates a new transformer.

Arguments

• source_crs - Source coordinate reference system
• target_crs - Target coordinate reference system

Errors

Returns an error if the transformation cannot be initialized.

pub fn from_epsg(source_epsg: u32, target_epsg: u32) -> Result<Self>

Creates a transformer from EPSG codes.

Arguments

• source_epsg - Source EPSG code
• target_epsg - Target EPSG code

Errors

Returns an error if the EPSG codes are invalid or transformation cannot be initialized.

pub fn source_crs(&self) -> &Crs

Returns the source CRS.

pub fn target_crs(&self) -> &Crs

Returns the target CRS.

pub fn transform(&self, coord: &Coordinate) -> Result<Coordinate>

Transforms a single coordinate.

Arguments

• coord - Input coordinate in source CRS

Errors

Returns an error if the transformation fails.

pub fn transform_3d(&self, coord: &Coordinate3D) -> Result<Coordinate3D>

Transforms a 3D coordinate.

pub fn transform_batch(&self, coords: &[Coordinate]) -> Result<Vec<Coordinate>>

Transforms multiple coordinates in batch.

This is more efficient than transforming one-by-one for large datasets.

Arguments

• coords - Input coordinates in source CRS

Errors

Returns an error if any transformation fails.

pub fn transform_bbox(&self, bbox: &BoundingBox) -> Result<BoundingBox>

Transforms a bounding box.

This transforms all four corners and creates a new bounding box from the results.

Arguments

• bbox - Input bounding box in source CRS

Errors

Returns an error if the transformation fails.
