Struct Force2D 

pub struct Force2D {
    pub x: f64,
    pub y: f64,
}

A validated planar force value.

Fields

x: f64

Horizontal force component.

y: f64

Vertical force component.

Implementations

impl Force2D

pub fn new(x: f64, y: f64) -> Option<Force2D>

Creates a new planar force when both components are finite.

pub fn magnitude(&self) -> Option<f64>

Returns the magnitude of this force.

Examples

use use_statics::Force2D;

assert_eq!(Force2D::new(3.0, 4.0).and_then(|force| force.magnitude()), Some(5.0));

pub fn angle_radians(&self) -> Option<f64>

Returns the planar angle of this force in radians.

Trait Implementations

impl Clone for Force2D

fn clone(&self) -> Force2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Force2D

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

Formats the value using the given formatter.

impl PartialEq for Force2D

fn eq(&self, other: &Force2D) -> 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.
