Struct nannou::ui::prelude::widget::primitive::shape::triangles::Triangle

pub struct Triangle<V>(pub [V; 3])
 where
    V: Vertex;

A single triangle described by three vertices.

Implementations

impl<V> Triangle<V> where
    V: Vertex, 

pub fn add(self, amount: [f64; 2]) -> Triangle<V>

Shift the triangle by the given amount by adding it onto the position of each point.

pub fn points(self) -> [[f64; 2]; 3]

The three points that make up the triangle.

impl Triangle<[f64; 2]>

pub fn color(self, a: Rgba, b: Rgba, c: Rgba) -> Triangle<([f64; 2], Rgba)>

Convert the Triangle<Point> to a Triangle<ColoredPoint>.

pub fn color_all(self, color: Rgba) -> Triangle<([f64; 2], Rgba)>

Convert the Triangle<Point> to a Triangle<ColoredPoint> using the given color.

Methods from Deref<Target = [V; 3]>

pub fn as_slice(&self) -> &[T]

🔬 This is a nightly-only experimental API. (array_methods)

Returns a slice containing the entire array. Equivalent to &s[..].

pub fn each_ref(&self) -> [&T; N]

🔬 This is a nightly-only experimental API. (array_methods)

Borrows each element and returns an array of references with the same size as self.

Example

#![feature(array_methods)]

let floats = [3.1, 2.7, -1.0];
let float_refs: [&f64; 3] = floats.each_ref();
assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);

This method is particularly useful if combined with other methods, like map. This way, you can avoid moving the original array if its elements are not Copy.

#![feature(array_methods, array_map)]

let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()];
let is_ascii = strings.each_ref().map(|s| s.is_ascii());
assert_eq!(is_ascii, [true, false, true]);

// We can still access the original array: it has not been moved.
assert_eq!(strings.len(), 3);
