Struct Polygons 

pub struct Polygons { /* private fields */ }

Collection of polygon geometries.

Implementations

impl Polygons

pub fn num_polygons(&self) -> usize

Return the number of polygons in this.

pub fn polygons(&self) -> Iter<'_, Vec<Vec<Vec<f64>>>>

Return an iterator over this polygons’ coordinates.

Trait Implementations

impl Clone for Polygons

fn clone(&self) -> Polygons

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Polygons

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

Formats the value using the given formatter.

impl Display for Polygons

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

Formats the value using the given formatter.

impl GTrait for Polygons

fn is_2d(&self) -> bool

Return TRUE if coordinates are 2D. Return FALSE otherwise.

fn to_wkt_fmt(&self, precision: usize) -> String

Generate a WKT string similar to the to_wkt()alternative but w/ a given precision paramter representing the number of digits to print after the decimal point. Note though that if precision is 0 only the integer part of the coordinate will be shown.

fn check_coordinates(&self, crs: &CRS) -> Result<(), MyError>

Check if all geometry coordinates fall w/in a given CRS’s Area-of-Use, aka Extent-of-Validity.

fn type_(&self) -> &str

Return the name/type of this geometry.

fn srid(&self) -> SRID

Return the Spatial Reference IDentifier of this.

fn to_wkt(&self) -> String

Generate a WKT string representing this.

impl PartialEq for Polygons

fn eq(&self, other: &Polygons) -> 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 PartialOrd for Polygons

fn partial_cmp(&self, other: &Polygons) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<ConstGeometry<'_>> for Polygons

type Error = MyError

The type returned in the event of a conversion error.

fn try_from(value: ConstGeometry<'_>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Geometry> for Polygons

type Error = MyError

The type returned in the event of a conversion error.

fn try_from(value: Geometry) -> Result<Self, Self::Error>

Performs the conversion.
