Struct CrsTransformer 

pub struct CrsTransformer { /* private fields */ }

Transformer for coordinate reference system conversions

This is a placeholder structure. In a full implementation, this would integrate with oxigdal-proj or proj4rs for actual transformations.

Implementations

impl CrsTransformer

pub fn new( source_crs: impl Into<String>, target_crs: impl Into<String>, ) -> Result<Self>

Creates a new CRS transformer

Arguments

• source_crs - Source CRS (e.g., “EPSG:4326”)
• target_crs - Target CRS (e.g., “EPSG:3857”)

Returns

A new transformer

Errors

Returns error if CRS definitions are invalid

pub fn from_common(source: CommonCrs, target: CommonCrs) -> Result<Self>

Creates a transformer from common CRS types

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

Transforms a single coordinate

Arguments

• coord - Input coordinate in source CRS

Returns

Transformed coordinate in target CRS

Errors

Returns error if transformation fails

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

Transforms multiple coordinates efficiently

pub fn transform_point(&self, point: &Point) -> Result<Point>

Transforms a point

pub fn transform_linestring( &self, linestring: &LineString, ) -> Result<LineString>

Transforms a linestring

pub fn transform_polygon(&self, polygon: &Polygon) -> Result<Polygon>

Transforms a polygon

pub fn transform_geometry(&self, geometry: &Geometry) -> Result<Geometry>

Transforms a geometry
