Implementations

impl BoundingRect

pub fn new_x_y_w_h(x: i32, y: i32, w: i32, h: i32) -> BoundingRect

pub fn width(self) -> i32

pub fn height(self) -> i32

pub fn is_empty(self) -> bool

pub fn center(self) -> Point2<i32>

pub fn left_top(&self) -> Point2<i32>

pub fn top_left(&self) -> Point2<i32>

pub fn top_right(&self) -> Point2<i32>

pub fn bottom_left(&self) -> Point2<i32>

pub fn right_bottom(&self) -> Point2<i32>

pub fn bottom_right(&self) -> Point2<i32>

pub fn sq_dist(self, other: BoundingRect) -> i32

Calculates the squared distance betweeen the center of two BoundingRects.

pub fn aspect_ratio(self) -> f64

pub fn aspect_ratio_doubled(self) -> i32

pub fn add_x_y(&mut self, x: i32, y: i32)

pub fn merge(&mut self, other: BoundingRect)

pub fn clear(&mut self)

pub fn hit(self, other: BoundingRect) -> bool

pub fn clip(&mut self, other: BoundingRect)

pub fn squared(self) -> BoundingRect

pub fn translate(&mut self, p: Point2<i32>)

pub fn have_point_on_boundary(&self, p: Point2<i32>, tolerance: usize) -> bool

Tolerance means: 1. Extend each boundary on both sides by tolerance units along its direction. 2. true is returned iff p lies on either one of the extended boundaries.

A point p lying on boundary “strictly” means this function returns true with p and tolerance set as 0.

pub fn have_point_inside(&self, p: Point2<i32>) -> bool

pub fn have_point_on_boundary_or_inside( &self, p: Point2<i32>, boundary_tolerance: usize, ) -> bool

For definition of boundary_tolerance, see BoundingRect::have_point_on_boundary().

pub fn get_closest_point_inside(&self, p: Point2<i32>) -> Point2<i32>

Given a point on the boundary, return the closest point inside the bounding rect. The behavior is undefined unless ‘p’ is a point on boundary (strictly) and the area of this rect is larger than 1.

pub fn get_closest_point_outside(&self, p: Point2<i32>) -> Point2<i32>

Given a point on the boundary, return the closest point outside the bounding rect. Note that if ‘p’ is a corner, there are three closest points, but the diagonal one is always returned. The behavior is undefined unless ‘p’ is a point on boundary (strictly).

pub fn get_boundary_points_from( &self, p: Point2<i32>, clockwise: bool, ) -> Vec<Point2<i32>>

Starting from ‘p’, copy the boundary points into a new Vec following the orientation specified by ‘clockwise’ and return it. The behavior is undefined unless ‘p’ is a point on boundary (strictly).

Trait Implementations

impl Bound for BoundingRect

fn bound(&self) -> BoundingRect

fn overlaps<B>(&self, other: &B) -> bool

where B: Bound,

impl Clone for BoundingRect

fn clone(&self) -> BoundingRect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoundingRect

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

Formats the value using the given formatter.

impl Default for BoundingRect

fn default() -> BoundingRect

Returns the “default value” for a type.

impl PartialEq for BoundingRect

fn eq(&self, other: &BoundingRect) -> 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.
