Struct vek::geom::repr_c::Rect [−][src]
pub struct Rect<P, E> {
pub x: P,
pub y: P,
pub w: E,
pub h: E,
}
Expand description
2D rectangle, represented by a bottom-left position, and 2D extents.
Most operations on a Rect
are better done by converting it to
Aabr
form. In fact, most existing code in the wild implicitly does this
and so does this crate.
Aabr
structs are often more convenient, faster and probably less confusing.
The Rect
type is provided because it exists for a lot of APIs (including
some system APIs, OpenGL, and others).
Please note that in most APIs in the wild (but NOT in vek
), the Y axis
is treated as pointing downwards because it’s the one of window space.
Keeping the Y axis upwards is a lot more convenient implementation-wise, and still matches the convention used in 3D spaces.
Fields
x: P
X position of the bottom-left corner.
y: P
Y position of the bottom-left corner.
w: E
Width.
h: E
Height, with Y axis going upwards.
Implementations
Creates a new rectangle from position elements and extent elements.
Gets this rectangle’s position and extent (size).
Returns this rectangle, converted with the given closures (one for position elements, the other for extent elements).
pub fn as_<DP, DE>(self) -> Rect<DP, DE> where
P: AsPrimitive<DP>,
DP: 'static + Copy,
E: AsPrimitive<DE>,
DE: 'static + Copy,
pub fn as_<DP, DE>(self) -> Rect<DP, DE> where
P: AsPrimitive<DP>,
DP: 'static + Copy,
E: AsPrimitive<DE>,
DE: 'static + Copy,
Converts this rectangle to a rectangle of another type, using the as
conversion.
Converts this into the matching axis-aligned bounding shape representation.
Does this rectangle contain the given point ?
Does this rectangle fully contain the given one ?
Does this rectangle collide with another ?
Returns this shape so that it contains the given point.
Expands this shape so that it contains the given point.
Gets the smallest rectangle that contains both this one and another.
Gets the largest rectangle contained by both this one and another.
Sets this rectangle to the union of itself with another.
Sets this rectangle to the intersection of itself with another.
pub fn collision_vector_with_rect(self, other: Self) -> Vec2<T> where
T: One + Div<T, Output = T>,
pub fn collision_vector_with_rect(self, other: Self) -> Vec2<T> where
T: One + Div<T, Output = T>,
Gets a vector that tells how much self
penetrates other
.
Splits this shape in two, by a straight plane along the
x
axis.
The returned tuple is (low, high)
.
Panics
sp
is assumed to be a position along the
x
axis that is within this shape’s bounds.
Splits this shape in two, by a straight plane along the
y
axis.
The returned tuple is (low, high)
.
Panics
sp
is assumed to be a position along the
y
axis that is within this shape’s bounds.
