Struct Point2D 

pub struct Point2D {
    pub x: f32,
    pub y: f32,
}

Vector used for referencing a point in 2D space.

Fields

x: f32

X value.

y: f32

Y value.

Implementations

impl Point2D

pub fn distance_from_plane(&self, plane: &Plane2D) -> f32

Calculate the distance the point is from the plane.

The value is positive if the point is in front of the plane, zero if intersecting, or negative if behind.

pub fn distance_from_point_squared(&self, point: &Point2D) -> f32

Calculate the distance the point is from another point. The value is returned squared for performance.

pub fn scale(&self, by: f32) -> Point2D

Scale the vector and return the result.

Trait Implementations

impl Clone for Point2D

fn clone(&self) -> Point2D

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Point2D

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Point2D

fn default() -> Point2D

Returns the “default value” for a type.

impl From<Point2D> for Vector2D

fn from(item: Point2D) -> Self

Converts to this type from the input type.

impl From<Vector2D> for Point2D

fn from(item: Vector2D) -> Self

Converts to this type from the input type.

impl PartialEq for Point2D

fn eq(&self, other: &Point2D) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TagSerialize for Point2D

fn tag_size() -> usize

Get the size of the data

fn into_tag( &self, data: &mut Vec<u8>, at: usize, struct_end: usize, ) -> ErrorMessageResult<()>

Serialize the data into tag format, returning an error on failure (except for out-of-bounds and allocation errors which will panic).

fn from_tag( data: &[u8], at: usize, struct_end: usize, _: &mut usize, ) -> ErrorMessageResult<Self>

Deserialize the data from tag format, returning an error on failure (except for allocation errors which will panic).

fn into_tag_cached( &self, data: &mut [u8], at: usize, struct_end: usize, ) -> ErrorMessageResult<()>

where Self: Sized,

Serialize the data into tag format in little endian, returning an error on failure (except for out-of-bounds and allocation errors which will panic).

fn from_tag_cached( data: &[u8], at: usize, struct_end: usize, ) -> ErrorMessageResult<Self>

where Self: Sized,

Deserialize the data from tag format from little endian, returning an error on failure (except for allocation errors which will panic).
