Struct Triangle

pub struct Triangle {
    pub p1: Point,
    pub p2: Point,
    pub p3: Point,
}

Triangle primitive

Examples

The macro examples make for more concise code.

Create some triangles with different styles

use embedded_graphics::{
    pixelcolor::Rgb565, prelude::*, primitives::Triangle, style::PrimitiveStyle,
};

// Triangle with red 1 px wide stroke
Triangle::new(Point::new(50, 20), Point::new(60, 35), Point::new(70, 80))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::RED, 1))
    .draw(&mut display)?;

// Triangle with translation applied
Triangle::new(Point::new(50, 20), Point::new(60, 35), Point::new(70, 80))
    .translate(Point::new(65, 35))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::GREEN, 1))
    .draw(&mut display)?;

Create a triangle from an array of points

use embedded_graphics::{geometry::Point, primitives::Triangle};

let p1 = Point::new(5, 10);
let p2 = Point::new(15, 25);
let p3 = Point::new(5, 25);

// Owned
let tri = Triangle::from_points([p1, p2, p3]);

// Or borrowed
let tri_ref = Triangle::from_points(&[p1, p2, p3]);

Fields

p1: Point

First point of the triangle

p2: Point

Second point of the triangle

p3: Point

Third point of the triangle

Implementations

impl Triangle

pub const fn new(p1: Point, p2: Point, p3: Point) -> Self

Create a new triangle with a given style

pub fn from_points<P, I>(points: P) -> Self

where I: Into<Point> + Copy, P: Borrow<[I; 3]>,

Creates a new triangle from an array of points.

This supports both Points, as well as anything that implements Into<Point> like (i32, i32).

Trait Implementations

impl Clone for Triangle

fn clone(&self) -> Triangle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Triangle

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

Formats the value using the given formatter.

impl Default for Triangle

fn default() -> Triangle

Returns the “default value” for a type.

impl Dimensions for Triangle

fn top_left(&self) -> Point

Get the top left corner of the bounding box for an object

fn bottom_right(&self) -> Point

Get the bottom right corner of the bounding box for an object

fn size(&self) -> Size

Get the width and height for an object

impl Hash for Triangle

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 Ord for Triangle

fn cmp(&self, other: &Triangle) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Triangle

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

fn partial_cmp(&self, other: &Triangle) -> 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 Primitive for Triangle

fn into_styled<C>( self, style: PrimitiveStyle<C>, ) -> Styled<Self, PrimitiveStyle<C>>

where C: PixelColor, Self: Sized,

Converts this primitive into a Styled.

impl Transform for Triangle

fn translate(&self, by: Point) -> Self

Translate the triangle from its current position to a new position by (x, y) pixels, returning a new Triangle. For a mutating transform, see translate_mut.

let tri = Triangle::new(Point::new(5, 10), Point::new(15, 20), Point::new(8, 15));
let moved = tri.translate(Point::new(10, 10));

assert_eq!(moved.p1, Point::new(15, 20));
assert_eq!(moved.p2, Point::new(25, 30));
assert_eq!(moved.p3, Point::new(18, 25));

fn translate_mut(&mut self, by: Point) -> &mut Self

Translate the triangle from its current position to a new position by (x, y) pixels.

let mut tri = Triangle::new(Point::new(5, 10), Point::new(15, 20), Point::new(10, 15));
tri.translate_mut(Point::new(10, 10));

assert_eq!(tri.p1, Point::new(15, 20));
assert_eq!(tri.p2, Point::new(25, 30));
assert_eq!(tri.p3, Point::new(20, 25));

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
