Trait mappers::Projection

pub trait Projection: Debug + DynClone + Send + Sync {
    fn project_unchecked(&self, lon: f64, lat: f64) -> (f64, f64);
    fn inverse_project_unchecked(&self, x: f64, y: f64) -> (f64, f64);

    fn project(&self, lon: f64, lat: f64) -> Result<(f64, f64), ProjectionError> { ... }
    fn inverse_project(
        &self,
        x: f64,
        y: f64
    ) -> Result<(f64, f64), ProjectionError> { ... }
}

An interface for all projections included in the crate.

This trait is kept as simple as possible and the most basic version of projection functions are implemented. Alternative functions for more complex types should be implemented by the user.

Required Methods

fn project_unchecked(&self, lon: f64, lat: f64) -> (f64, f64)

Same as Projection::project() but does not check the result.

fn inverse_project_unchecked(&self, x: f64, y: f64) -> (f64, f64)

Same as Projection::inverse_project() but does not check the result.

Provided Methods

fn project(&self, lon: f64, lat: f64) -> Result<(f64, f64), ProjectionError>

Function to project geographical coordinates (in degrees) to cartographical coordinates (in meters) on a map with specified projection.

Errors

Returns ProjectionError::ProjectionImpossible when result of projection is not finite.

fn inverse_project(&self, x: f64, y: f64) -> Result<(f64, f64), ProjectionError>

Function to inversly project cartographical coordinates (in meters) to geographical coordinates (in degrees) on a map with specified projection.

Errors

Returns ProjectionError::InverseProjectionImpossible when result of inverse projection is not finite.
