Struct geo_types::Line [−][src]
pub struct Line<T> where
T: CoordinateType, { pub start: Coordinate<T>, pub end: Coordinate<T>, }
A line segment made up of exactly two Point
s
Fields
start: Coordinate<T>
end: Coordinate<T>
Methods
impl<T> Line<T> where
T: CoordinateType,
[src]
impl<T> Line<T> where
T: CoordinateType,
pub fn new<C>(start: C, end: C) -> Line<T> where
C: Into<Coordinate<T>>,
[src]
pub fn new<C>(start: C, end: C) -> Line<T> where
C: Into<Coordinate<T>>,
Creates a new line segment.
Examples
use geo_types::{Coordinate, Line}; let line = Line::new( Coordinate { x: 0., y: 0. }, Coordinate { x: 1., y: 2. }, ); assert_eq!(line.start, Coordinate { x: 0., y: 0. }); assert_eq!(line.end, Coordinate { x: 1., y: 2. });
pub fn dx(&self) -> T
[src]
pub fn dx(&self) -> T
Calculate the difference in ‘x’ components (Δx).
Equivalent to:
line.end.x - line.start.x
pub fn dy(&self) -> T
[src]
pub fn dy(&self) -> T
Calculate the difference in ‘y’ components (Δy).
Equivalent to:
line.end.y - line.start.y
pub fn slope(&self) -> T
[src]
pub fn slope(&self) -> T
Calculate the slope (Δy/Δx).
Equivalent to:
line.dy() / line.dx()
Note that:
Line::new(a, b).slope() == Line::new(b, a).slope()
pub fn determinant(&self) -> T
[src]
pub fn determinant(&self) -> T
Calculate the determinant of the line.
Equivalent to:
line.start.x * line.end.y - line.start.y * line.end.x
Note that:
Line::new(a, b).determinant() == -Line::new(b, a).determinant()
pub fn start_point(&self) -> Point<T>
[src]
pub fn start_point(&self) -> Point<T>
pub fn end_point(&self) -> Point<T>
[src]
pub fn end_point(&self) -> Point<T>
pub fn points(&self) -> (Point<T>, Point<T>)
[src]
pub fn points(&self) -> (Point<T>, Point<T>)
