Convert into a 3d point.

impl<T, U> TypedPoint2D<T, U>

pub fn new(x: T, y: T) -> Self

Constructor taking scalar values directly.

impl<T: Copy, U> TypedPoint2D<T, U>

pub fn from_lengths(x: Length<T, U>, y: Length<T, U>) -> Self

Constructor taking properly typed Lengths instead of scalar values.

pub fn extend(&self, z: T) -> TypedPoint3D<T, U>

Create a 3d point from this one, using the specified z value.

pub fn to_vector(&self) -> TypedVector2D<T, U>

Cast this point into a vector.

Equivalent to subtracting the origin from this point.

pub fn yx(&self) -> Self

Swap x and y.

pub fn x_typed(&self) -> Length<T, U>

Returns self.x as a Length carrying the unit.

pub fn y_typed(&self) -> Length<T, U>

Returns self.y as a Length carrying the unit.

pub fn to_untyped(&self) -> Point2D<T>

Drop the units, preserving only the numeric value.

pub fn from_untyped(p: &Point2D<T>) -> Self

Tag a unitless value with units.

pub fn to_array(&self) -> [T; 2]

impl<T: Copy + Add<T, Output = T>, U> TypedPoint2D<T, U>

pub fn add_size(&self, other: &TypedSize2D<T, U>) -> Self

impl<T: Float, U> TypedPoint2D<T, U>

pub fn min(self, other: Self) -> Self

pub fn max(self, other: Self) -> Self

impl<T: Round, U> TypedPoint2D<T, U>

pub fn round(&self) -> Self

Rounds each component to the nearest integer value.

This behavior is preserved for negative values (unlike the basic cast). For example { -0.1, -0.8 }.round() == { 0.0, -1.0 }.

impl<T: Ceil, U> TypedPoint2D<T, U>

pub fn ceil(&self) -> Self

Rounds each component to the smallest integer equal or greater than the original value.

This behavior is preserved for negative values (unlike the basic cast). For example { -0.1, -0.8 }.ceil() == { 0.0, 0.0 }.

impl<T: Floor, U> TypedPoint2D<T, U>

pub fn floor(&self) -> Self

Rounds each component to the biggest integer equal or lower than the original value.

This behavior is preserved for negative values (unlike the basic cast). For example { -0.1, -0.8 }.floor() == { -1.0, -1.0 }.

impl<T: NumCast + Copy, U> TypedPoint2D<T, U>

pub fn cast<NewT: NumCast + Copy>(&self) -> TypedPoint2D<NewT, U>

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(), ceil() or floor() before casting.

pub fn try_cast<NewT: NumCast + Copy>(&self) -> Option<TypedPoint2D<NewT, U>>

Fallible 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(), ceil() or floor() before casting.

pub fn to_f32(&self) -> TypedPoint2D<f32, U>

Cast into an f32 point.

pub fn to_f64(&self) -> TypedPoint2D<f64, U>

Cast into an f64 point.

pub fn to_usize(&self) -> TypedPoint2D<usize, U>

Cast into an usize point, truncating decimals if any.

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

pub fn to_u32(&self) -> TypedPoint2D<u32, U>

Cast into an u32 point, truncating decimals if any.

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

pub fn to_i32(&self) -> TypedPoint2D<i32, U>

Cast into an i32 point, truncating decimals if any.

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

pub fn to_i64(&self) -> TypedPoint2D<i64, U>

Cast into an i64 point, truncating decimals if any.

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

impl<T, U> TypedPoint2D<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 point and another point.

t is expected to be between zero and one.
