Trait FromGeoJSON

pub trait FromGeoJSON {
    type Err;

    // Required method
    fn from_geojson<T: FromSlice + CoordType + ToSFCGALGeom>(
        geom: &GeometryValue,
    ) -> Result<SFCGeometry>;
}

Conversion from GeoJson to SFCGAL Geometries.

Required Associated Types

type Err

Required Methods

fn from_geojson<T: FromSlice + CoordType + ToSFCGALGeom>( geom: &GeometryValue, ) -> Result<SFCGeometry>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl FromGeoJSON for SFCGeometry

Conversion from GeoJson to SFCGAL geometries.

Allows to choose if the constructed SFCGAL geometries will be 2d or 3d.

use sfcgal::{SFCGeometry, FromGeoJSON};
type Point2d = (f64, f64);

let geom = geojson::Geometry {
    bbox: None,
    value: geojson::Value::LineString(vec![vec![101.0, 0.0], vec![102.0, 1.0]]),
    foreign_members: None,
};
let line_sfcgal = SFCGeometry::from_geojson::<Point2d>(&geom.value).unwrap();

type Err = Error
