Struct geom::Ring

pub struct Ring {
    pts: Vec<Pt2D>,
}

Maybe a misnomer, but like a PolyLine, but closed.

Fields

pts: Vec<Pt2D>

Implementations

impl Ring

pub fn new(pts: Vec<Pt2D>) -> Result<Ring>

pub fn must_new(pts: Vec<Pt2D>) -> Ring

pub fn to_outline(&self, thickness: Distance) -> Polygon

Draws the ring with some thickness, with half of it straddling the interor of the ring, and half on the outside.

pub fn into_polygon(self) -> Polygon

pub fn points(&self) -> &Vec<Pt2D>

pub fn into_points(self) -> Vec<Pt2D>

pub fn all_intersections(&self, other: &PolyLine) -> Vec<Pt2D>

Be careful with the order of results. Hits on an earlier line segment of other show up first, but if the ring hits a line segment at multiple points, who knows. Dedupes.

pub(crate) fn get_both_slices_btwn(
    &self,
    pt1: Pt2D,
    pt2: Pt2D
) -> Option<(PolyLine, PolyLine)>

pub fn get_shorter_slice_btwn(&self, pt1: Pt2D, pt2: Pt2D) -> Option<PolyLine>

pub fn split_points(pts: &[Pt2D]) -> Result<(Vec<PolyLine>, Vec<Ring>)>

Extract all PolyLines and Rings. Doesn’t handle crazy double loops and stuff.

pub fn contains_pt(&self, pt: Pt2D) -> bool

pub fn to_geojson(&self, gps: Option<&GPSBounds>) -> Geometry

Produces a GeoJSON polygon, optionally mapping the world-space points back to GPS.

pub fn translate(self, dx: f64, dy: f64) -> Ring

Translates the ring by a fixed offset.

Trait Implementations

impl Clone for Ring

fn clone(&self) -> Ring

Returns a copy of the value.

impl Debug for Ring

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Ring

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
