Struct graphene::Quad

#[repr(transparent)]
pub struct Quad { /* private fields */ }

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

pub fn as_ptr(&self) -> *mut graphene_quad_t

pub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const graphene_quad_t) -> &'a Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut graphene_quad_t ) -> &'a mut Self

Borrows the underlying C value mutably.

impl Quad

pub fn bounds(&self) -> Rect

Computes the bounding rectangle of self and places it into r.

Returns

r

return location for a Rect

pub fn contains(&self, p: &Point) -> bool

Checks if the given Quad contains the given Point.

p

a Point

Returns

true if the point is inside the Quad

impl Quad

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 from_rect(r: &Rect) -> Self

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

r

a Rect

Returns

the initialized Quad

pub fn from_points(points: &[Point; 4]) -> Self

points

an array of 4 Point

Returns

the initialized Quad

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

Retrieves the point of a Quad at the given index.

index_

the index of the point to retrieve

Returns

a Point
