Struct graphene::Quad

pub struct Quad(_);

A 4 vertex quadrilateral, as represented by four Point.

The contents of a Quad are private and should never be accessed directly.

Implementations

impl Quad

p

a Point

Returns

true if the point is inside the Quad

pub fn point(&self, index_: u32) -> Option<Point>

Retrieves the point of a Quad at the given index.

index_

the index of the point to retrieve

Returns

a Point

pub fn init(&mut self, p1: &Point, p2: &Point, p3: &Point, p4: &Point)

Initializes a Quad with the given points.

p1

the first point of the quadrilateral

p2

the second point of the quadrilateral

p3

the third point of the quadrilateral

p4

the fourth point of the quadrilateral

Returns

the initialized Quad

pub fn init_from_rect(&mut self, r: &Rect)

Initializes a Quad using the four corners of the given Rect.

r

a Rect

Returns

the initialized Quad

impl Quad

pub fn init_from_points(&mut self, points: &[&Point; 4])

Initializes a Quad using an array of points.

points

an array of 4 Point

Returns

the initialized Quad

pub fn new(p1: &Point, p2: &Point, p3: &Point, p4: &Point) -> Quad

pub fn from_rect(r: &Rect) -> Quad
