Struct Point

pub struct Point(/* private fields */);

Implementations

impl Point

pub fn alloc() -> Point

Allocates a new Point.

Returns

the newly allocated Point. Use Point::free to free its resources.

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

Computes the distance between two Point.

b

a Point

x_distance

return location for the horizontal distance between the points

y_distance

return location for the vertical distance between the points

Returns

the distance between the points.

pub fn equals(&self, b: &Point) -> bool

Compares two Point for equality.

b

the second Point to compare

Returns

true if the ClutterPoints are equal

pub fn init(&mut self, x: f32, y: f32) -> Option<Point>

Initializes self with the given coordinates.

x

the X coordinate of the point

y

the Y coordinate of the point

Returns

the initialized Point

pub fn zero() -> Option<Point>

A point centered at (0, 0).

The returned value can be used as a guard.

Returns

a point centered in (0, 0); the returned Point is owned by Clutter and it should not be modified or freed.

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 Hash for Point

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Point

fn cmp(&self, other: &Point) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for Point

fn partial_cmp(&self, other: &Point) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for Point

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Point
