Struct Point 

pub struct Point {
    pub x: f64,
    pub y: f64,
}

A point in data space.

Use this when providing explicit X/Y values.

Fields

x: f64

X value in data coordinates.

y: f64

Y value in data coordinates.

Implementations

impl Point

pub fn new(x: f64, y: f64) -> Self

Create a new data point.

Trait Implementations

impl Clone for Point

fn clone(&self) -> Point

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Point

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

Formats the value using the given formatter.

impl PartialEq for Point

fn eq(&self, other: &Point) -> 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 Copy for Point
