pub fn new(origin: TypedPoint2D<T, U>, size: TypedSize2D<T, U>) -> Self

Constructor.

impl<T, U> TypedRect<T, U> where

pub fn translate(&self, by: &TypedVector2D<T, U>) -> Self

Returns the same rectangle, translated by a vector.

pub fn contains(&self, other: &TypedPoint2D<T, U>) -> bool

Returns true if this rectangle contains the point. Points are considered in the rectangle if they are on the left or top edge, but outside if they are on the right or bottom edge.

pub fn contains_rect(&self, rect: &Self) -> bool

Returns true if this rectangle contains the interior of rect. Always returns true if rect is empty, and always returns false if rect is nonempty but this rectangle is empty.

pub fn inflate(&self, width: T, height: T) -> Self

pub fn inflate_typed(&self, width: Length<T, U>, height: Length<T, U>) -> Self

pub fn top_right(&self) -> TypedPoint2D<T, U>

pub fn bottom_left(&self) -> TypedPoint2D<T, U>

pub fn bottom_right(&self) -> TypedPoint2D<T, U>

pub fn translate_by_size(&self, size: &TypedSize2D<T, U>) -> Self

pub fn from_points(points: &[TypedPoint2D<T, U>]) -> Self

Returns the smallest rectangle containing the four points.

impl<T, U> TypedRect<T, U> where
    T: Copy + One + Add<Output = T> + Sub<Output = T> + Mul<Output = T>, 

pub fn lerp(&self, other: Self, t: T) -> Self

Linearly interpolate between this rectangle and another rectangle.

t is expected to be between zero and one.

impl<T, U> TypedRect<T, U> where
    T: Copy + Clone + PartialOrd + Add<T, Output = T> + Sub<T, Output = T> + Zero, 

pub fn union(&self, other: &Self) -> Self

impl<T, U> TypedRect<T, U>

pub fn scale<S: Copy>(&self, x: S, y: S) -> Self where
    T: Copy + Clone + Mul<S, Output = T>, 

impl<T: Copy + PartialEq + Zero, U> TypedRect<T, U>

pub fn zero() -> Self

Constructor, setting all sides to zero.

pub fn is_empty(&self) -> bool

Returns true if the size is zero, regardless of the origin's value.

impl<T: Copy, Unit> TypedRect<T, Unit>

pub fn to_untyped(&self) -> Rect<T>

Drop the units, preserving only the numeric value.

pub fn from_untyped(r: &Rect<T>) -> TypedRect<T, Unit>

Tag a unitless value with units.

impl<T0: NumCast + Copy, Unit> TypedRect<T0, Unit>

pub fn cast<T1: NumCast + Copy>(&self) -> Option<TypedRect<T1, Unit>>

Cast from one numeric representation to another, preserving the units.

When casting from floating point to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), round_in or round_out() before casting.

impl<T: Floor + Ceil + Round + Add<T, Output = T> + Sub<T, Output = T>, U> TypedRect<T, U>

pub fn round(&self) -> Self

Return a rectangle with edges rounded to integer coordinates, such that the returned rectangle has the same set of pixel centers as the original one. Edges at offset 0.5 round up. Suitable for most places where integral device coordinates are needed, but note that any translation should be applied first to avoid pixel rounding errors. Note that this is not rounding to nearest integer if the values are negative. They are always rounding as floor(n + 0.5).

pub fn round_in(&self) -> Self

Return a rectangle with edges rounded to integer coordinates, such that the original rectangle contains the resulting rectangle.

pub fn round_out(&self) -> Self

Return a rectangle with edges rounded to integer coordinates, such that the original rectangle is contained in the resulting rectangle.

impl<T: NumCast + Copy, Unit> TypedRect<T, Unit>

pub fn to_f32(&self) -> TypedRect<f32, Unit>

Cast into an f32 rectangle.

pub fn to_f64(&self) -> TypedRect<f64, Unit>

Cast into an f64 rectangle.

pub fn to_usize(&self) -> TypedRect<usize, Unit>

Cast into an usize rectangle, truncating decimals if any.

When casting from floating point rectangles, it is worth considering whether to round(), round_in() or round_out() before the cast in order to obtain the desired conversion behavior.

pub fn to_i32(&self) -> TypedRect<i32, Unit>

Cast into an i32 rectangle, truncating decimals if any.

When casting from floating point rectangles, it is worth considering whether to round(), round_in() or round_out() before the cast in order to obtain the desired conversion behavior.

pub fn to_i64(&self) -> TypedRect<i64, Unit>

Cast into an i64 rectangle, truncating decimals if any.

When casting from floating point rectangles, it is worth considering whether to round(), round_in() or round_out() before the cast in order to obtain the desired conversion behavior.
