Struct graphene::Point

#[repr(transparent)]
pub struct Point { /* private fields */ }

A point with two coordinates.

Implementations

impl Point

pub fn as_ptr(&self) -> *mut graphene_point_t

impl Point

pub fn distance(&self, b: &Point) -> (f32, f32, f32)

Computes the distance between self and b.

b

a Point

Returns

the distance between the two points

d_x

distance component on the X axis

d_y

distance component on the Y axis

pub fn interpolate(&self, b: &Point, factor: f64) -> Point

Linearly interpolates the coordinates of self and b using the given factor.

b

a Point

factor

the linear interpolation factor

Returns

res

return location for the interpolated point

pub fn near(&self, b: &Point, epsilon: f32) -> bool

Checks whether the two points self and b are within the threshold of epsilon.

b

a Point

epsilon

threshold between the two points

Returns

true if the distance is within epsilon

pub fn to_vec2(&self) -> Vec2

Stores the coordinates of the given Point into a Vec2.

Returns

v

return location for the vertex

pub fn zero() -> Point

Returns a point fixed at (0, 0).

Returns

a fixed point

impl Point

pub fn new(x: f32, y: f32) -> Self

Initializes self to the given x and y coordinates.

It’s safe to call this function multiple times.

x

the X coordinate

y

the Y coordinate

Returns

the initialized point

pub fn from_vec2(src: &Vec2) -> Point

Initializes self with the coordinates inside the given Vec2.

src

a Vec2

Returns

the initialized point

pub fn x(&self) -> f32

pub fn set_x(&mut self, x: f32)

pub fn y(&self) -> f32

pub fn set_y(&mut self, y: f32)

Trait Implementations

impl Clone for Point

fn clone(&self) -> Self

Returns a copy 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<Point> for Point

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl StaticType for Point

fn static_type() -> Type

Returns the type identifier of Self.

impl Copy for Point

impl Eq for Point
