Struct SvgLine 

#[repr(C)]
pub struct SvgLine {
    pub start: SvgPoint,
    pub end: SvgPoint,
}

A line segment in 2D space.

Fields

start: SvgPoint

Start point of the line

end: SvgPoint

End point of the line

Implementations

impl SvgLine

pub const fn new(start: SvgPoint, end: SvgPoint) -> SvgLine

Creates a new line segment from start to end point

pub fn inwards_normal(&self) -> Option<SvgPoint>

Computes the inward-facing normal vector for this line.

The normal points 90 degrees to the right of the line direction. Returns None if the line has zero length.

pub fn outwards_normal(&self) -> Option<SvgPoint>

Computes the outward-facing normal vector for this line (opposite of inwards_normal).

pub fn reverse(&mut self)

Reverses the direction of the line by swapping start and end points.

pub fn get_start(&self) -> SvgPoint

Returns the start point of the line.

pub fn get_end(&self) -> SvgPoint

Returns the end point of the line.

pub fn get_t_at_offset(&self, offset: f64) -> f64

Returns the parametric t value (0.0–1.0) at the given arc-length offset.

pub fn get_tangent_vector_at_t(&self) -> SvgVector

Returns the tangent vector of the line. For a line, the tangent is constant (same direction everywhere), so no t parameter is needed.

pub fn get_x_at_t(&self, t: f64) -> f64

Returns the X coordinate at parametric position t (0.0 = start, 1.0 = end).

pub fn get_y_at_t(&self, t: f64) -> f64

Returns the Y coordinate at parametric position t (0.0 = start, 1.0 = end).

pub fn get_length(&self) -> f64

Returns the Euclidean length of the line segment.

pub fn get_bounds(&self) -> SvgRect

Returns the axis-aligned bounding rectangle of this line segment.

Trait Implementations

impl Clone for SvgLine

fn clone(&self) -> SvgLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SvgLine

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

Formats the value using the given formatter.

impl PartialEq for SvgLine

fn eq(&self, other: &SvgLine) -> 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 SvgLine

fn partial_cmp(&self, other: &SvgLine) -> 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.
