Struct WallSegment 

pub struct WallSegment {
    pub x1: f64,
    pub y1: f64,
    pub x2: f64,
    pub y2: f64,
}

A wall segment defined by two endpoints.

Wall segments are used for wall-repulsion force calculations. The closest point on the segment to the queried position is computed analytically.

Fields

x1: f64

Start point x.

y1: f64

Start point y.

x2: f64

End point x.

y2: f64

End point y.

Implementations

impl WallSegment

pub fn new(x1: f64, y1: f64, x2: f64, y2: f64) -> Self

Create a new wall segment from (x1, y1) to (x2, y2).

pub fn closest_point(&self, px: f64, py: f64) -> (f64, f64)

Closest point on this wall segment to point (px, py).

Uses the standard parametric line clamped to [0, 1].

Trait Implementations

impl Clone for WallSegment

fn clone(&self) -> WallSegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WallSegment

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

Formats the value using the given formatter.

impl PartialEq for WallSegment

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