Struct Line

pub struct Line<T> {
    pub s: Point<T>,
    pub e: Point<T>,
}

A lines segment of finite length, determined by a starting points and an ending points.

Fields

s: Point<T>

Start points of the lines segment.

e: Point<T>

End points of the lines segment.

pub fn length(&self) -> T

where T: Real,

Get the length of the line

pub fn as_vector(&self) -> Vector<T>

Trait Implementations

impl<T> Clone for Line<T>

where T: Clone,

fn clone(&self) -> Line<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Line<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Line<T>

where T: Zero + One,

fn default() -> Line<T>

Returns the “default value” for a type.

impl<T> EuclideanDistance<T, Line<T>> for Point<T>

where T: Float,

fn euclidean_distance(&self, rhs: &Line<T>) -> T

fn euclidean_squared(&self, rhs: &Line<T>) -> T

It is especially suitable when only the length needs to be compared

impl<T> Hash for Line<T>

where T: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq for Line<T>

where T: PartialEq,

fn eq(&self, other: &Line<T>) -> 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.
