Geometry processing trait

Provided methods

fn dimensions(&self) -> CoordDimensions

Additional dimensions requested when processing coordinates

fn xy(&mut self, x: f64, y: f64, idx: usize) -> Result<()>

Process coordinate with x,y dimensions

fn coordinate(
    &mut self,
    x: f64,
    y: f64,
    z: Option<f64>,
    m: Option<f64>,
    t: Option<f64>,
    tm: Option<u64>,
    idx: usize
) -> Result<()>

Process coordinate with all requested dimensions

fn point_begin(&mut self, idx: usize) -> Result<()>

Begin of Point processing

Next: xy/coordinate

fn point_end(&mut self, idx: usize) -> Result<()>

End of Point processing

fn multipoint_begin(&mut self, size: usize, idx: usize) -> Result<()>

Begin of MultiPoint processing

Next: size * xy/coordinate

End of MultiLineString processing

fn polygon_begin(&mut self, tagged: bool, size: usize, idx: usize) -> Result<()>

Begin of Polygon processing

An untagged Polygon is part of a MultiPolygon

Next: size * LineString (untagged) = rings
