Struct MotionVector 

pub struct MotionVector {
    pub dy: f64,
    pub dx: f64,
}

A 2-D motion vector (displacement in row/col directions).

Fields

dy: f64

Row displacement (positive = downward).

dx: f64

Column displacement (positive = rightward).

Implementations

impl MotionVector

pub fn new(dy: f64, dx: f64) -> Self

Create a new motion vector.

pub fn zero() -> Self

Zero motion.

pub fn magnitude(&self) -> f64

Magnitude of the motion vector.

pub fn angle(&self) -> f64

Direction in radians.

Trait Implementations

impl Clone for MotionVector

fn clone(&self) -> MotionVector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MotionVector

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

Formats the value using the given formatter.

impl PartialEq for MotionVector

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