Implementations

impl G

pub fn as_point(&self) -> Option<&Point>

pub fn as_line(&self) -> Option<&Line>

Return this if it was indeed a Line, None otherwise.

pub fn as_polygon(&self) -> Option<&Polygon>

Return this if it was indeed a Polygon, None otherwise.

pub fn as_points(&self) -> Option<&Points>

Return this if it was indeed a Point collection, None otherwise.

pub fn as_lines(&self) -> Option<&Lines>

Return this if it was indeed a Line collection, None otherwise.

pub fn as_polygons(&self) -> Option<&Polygons>

Return this if it was indeed a Polygon collection, None otherwise.

Trait Implementations

impl Clone for G

fn clone(&self) -> G

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for G

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

Formats the value using the given formatter.

impl Default for G

fn default() -> G

Returns the “default value” for a type.

impl Display for G

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

Formats the value using the given formatter.

impl GTrait for G

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 G

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for G

fn partial_cmp(&self, other: &G) -> 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.
