Implementations

impl ILine

pub const ZERO: Self

pub fn new<P>(start: P, end: P) -> Self

where P: Into<IVec2>,

Creates a new line with the given start and end points.

pub fn start(&self) -> IVec2

Get the start point.

pub fn end(&self) -> IVec2

Get the end point.

pub fn length_squared(&self) -> f32

Get the line’s length squared.

pub fn length(&self) -> f32

Get the line’s length.

pub fn distance_squared_to_point(&self, p: Vec2) -> f32

pub fn distance_to_point(&self, p: Vec2) -> f32

pub fn rotate(&self, radians: f32) -> Self

Create a new line that is the rotation of this line around its start point, by the given radians.

pub fn rotate_around(&self, center: IVec2, radians: f32) -> Self

Create a new line that is the rotation of this line around the given point, by the given radians.

pub fn flip(&self) -> Self

Flip the orientation of the line such that the start point becomes the end point and vice versa.

pub fn contains<P>(&self, point: P) -> bool

where P: Into<Vec2>,

Determine if the given point lies on this line.

pub fn is_vertical(&self) -> bool

pub fn is_horizontal(&self) -> bool

pub fn is_axis_aligned(&self) -> bool

Determine if this line is axis-aligned.

pub fn aabb(&self) -> IRect

Get the axis-aligned bounding box of this line.

pub fn axis_alignment(&self) -> Option<Direction>

Get the axis-aligned direction of this line, if it is axis-aligned, None otherwise.

pub fn diagonal_axis_alignment(&self) -> Option<Direction>

Get the diagonal axis-aligned direction of this line, if it is diagonally axis-aligned, None otherwise.

pub fn intersects_line(&self, other: &ILine) -> Option<IVec2>

Determine if this line intersects the given line.

pub fn intersects_rect(&self, rect: &IRect) -> bool

Determine if this line intersects the edges of, or is contained within the given rectangle.

pub fn axis_aligned_intersect_rect(&self, rect: &IRect) -> Option<ILine>

Obtain the segment of this line that intersects the given rectangle, if any, otherwise None. This line must be axis-aligned, otherwise None is returned.

pub fn overlap(&self, other: &ILine) -> Option<ILine>

If this and the given line segments overlap, return the overlapping segment. Otherwise, return None.

pub fn visit_points<F>(&self, visitor: F)

where F: FnMut(i32, i32),

Use Bresenham’s line algorithm to visit points on this line.

pub fn pixels(&self) -> LinePixelIterator

Trait Implementations

impl Clone for ILine

fn clone(&self) -> ILine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ILine

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

Formats the value using the given formatter.

impl Default for ILine

fn default() -> ILine

Returns the “default value” for a type.

impl Display for ILine

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

Formats the value using the given formatter.

impl From<&ILine> for [IVec2; 2]

fn from(value: &ILine) -> Self

Converts to this type from the input type.

impl From<&ILine> for [Vec2; 2]

fn from(value: &ILine) -> Self

Converts to this type from the input type.

impl PartialEq for ILine

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