Struct Polygon 

pub struct Polygon {
    pub exterior: Vec<(f64, f64)>,
    pub interiors: Vec<Vec<(f64, f64)>>,
    pub srid: Option<i32>,
}

A polygon (list of points forming a closed ring).

Fields

exterior: Vec<(f64, f64)>

Exterior ring coordinates.

interiors: Vec<Vec<(f64, f64)>>

Interior rings (holes).

srid: Option<i32>

SRID.

Implementations

impl Polygon

pub fn new(exterior: Vec<(f64, f64)>) -> Self

Create a new polygon from coordinates.

pub fn with_hole(self, hole: Vec<(f64, f64)>) -> Self

Add an interior ring (hole).

pub fn with_srid(self, srid: i32) -> Self

Set SRID.

pub fn to_wkt(&self) -> String

Generate WKT (Well-Known Text).

pub fn to_postgis(&self) -> String

Generate PostGIS polygon.

pub fn to_geojson(&self) -> Value

Generate GeoJSON.

Trait Implementations

impl Clone for Polygon

fn clone(&self) -> Polygon

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Polygon

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Polygon

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Polygon

fn eq(&self, other: &Polygon) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Polygon

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
