Struct geo_types::geometry::Triangle

pub struct Triangle<T: CoordNum = f64>(pub Coord<T>, pub Coord<T>, pub Coord<T>);

A bounded 2D area whose three vertices are defined by Coords. The semantics and validity are that of the equivalent Polygon; in addition, the three vertices must not be collinear and they must be distinct.

Tuple Fields

0: Coord<T>

1: Coord<T>

2: Coord<T>

Implementations

impl<T: CoordNum> Triangle<T>

pub fn new(v1: Coord<T>, v2: Coord<T>, v3: Coord<T>) -> Self

Instantiate Self from the raw content value

pub fn to_array(&self) -> [Coord<T>; 3]

pub fn to_lines(&self) -> [Line<T>; 3]

pub fn to_polygon(self) -> Polygon<T>

Create a Polygon from the Triangle.

Examples

use geo_types::{coord, Triangle, polygon};

let triangle = Triangle::new(
    coord! { x: 0., y: 0. },
    coord! { x: 10., y: 20. },
    coord! { x: 20., y: -10. },
);

assert_eq!(
    triangle.to_polygon(),
    polygon![
        (x: 0., y: 0.),
        (x: 10., y: 20.),
        (x: 20., y: -10.),
        (x: 0., y: 0.),
    ],
);

Trait Implementations

impl<T: Clone + CoordNum> Clone for Triangle<T>

fn clone(&self) -> Triangle<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + CoordNum> Debug for Triangle<T>

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

Formats the value using the given formatter.

impl<IC: Into<Coord<T>> + Copy, T: CoordNum> From<[IC; 3]> for Triangle<T>

fn from(array: [IC; 3]) -> Self

Converts to this type from the input type.

impl<T: CoordNum> From<Triangle<T>> for Geometry<T>

fn from(x: Triangle<T>) -> Self

Converts to this type from the input type.

impl<T: CoordNum> From<Triangle<T>> for Polygon<T>

fn from(t: Triangle<T>) -> Self

Converts to this type from the input type.

impl<T: Hash + CoordNum> Hash for Triangle<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq + CoordNum> PartialEq for Triangle<T>

fn eq(&self, other: &Triangle<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T: CoordNum> TryFrom<Geometry<T>> for Triangle<T>

Convert a Geometry enum into its inner type.

Fails if the enum case does not match the type you are trying to convert it to.

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
