Methods

impl<T, U> TypedPoint2D<T, U> where
    T: Zero + Copy, 

fn origin() -> TypedPoint2D<T, U>

Constructor, setting all components to zero.

fn zero() -> TypedPoint2D<T, U>

fn to_3d(&self) -> TypedPoint3D<T, U>

Convert into a 3d point.

impl<T, U> TypedPoint2D<T, U> where
    T: Copy, 

fn new(x: T, y: T) -> TypedPoint2D<T, U>

Constructor taking scalar values directly.

fn from_lengths(x: Length<T, U>, y: Length<T, U>) -> TypedPoint2D<T, U>

Constructor taking properly typed Lengths instead of scalar values.

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

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

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

Cast this point into a vector.

Equivalent to subtracting the origin from this point.

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

Swap x and y.

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

Returns self.x as a Length carrying the unit.

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

Returns self.y as a Length carrying the unit.

fn to_untyped(&self) -> TypedPoint2D<T, UnknownUnit>

Drop the units, preserving only the numeric value.

fn from_untyped(p: &TypedPoint2D<T, UnknownUnit>) -> TypedPoint2D<T, U>

Tag a unitless value with units.

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

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

fn add_size(&self, other: &TypedSize2D<T, U>) -> TypedPoint2D<T, U>

impl<T, U> TypedPoint2D<T, U> where
    T: Float, 

fn min(self, other: TypedPoint2D<T, U>) -> TypedPoint2D<T, U>

fn max(self, other: TypedPoint2D<T, U>) -> TypedPoint2D<T, U>

impl<T, U> TypedPoint2D<T, U> where
    T: Round, 

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

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, U> TypedPoint2D<T, U> where
    T: Ceil, 

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

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, U> TypedPoint2D<T, U> where
    T: Floor, 

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

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

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

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.

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

Cast into an f32 point.

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

Cast into an f64 point.

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.

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.

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: One + Add<T, Output = T> + Sub<T, Output = T> + Mul<T, Output = T> + Copy, 

fn lerp(&self, other: TypedPoint2D<T, U>, t: T) -> TypedPoint2D<T, U>

Linearly interpolate between this point and another point.

t is expected to be between zero and one.
