Struct Body 

#[non_exhaustive]
pub struct Body {
    pub position: [f64; 3],
    pub velocity: [f64; 3],
    pub mass: f64,
    pub mu: Option<f64>,
}

A gravitating body with position, velocity, and mass.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

position: [f64; 3]

Position [x, y, z] (metres).

velocity: [f64; 3]

Velocity [vx, vy, vz] (m/s).

mass: f64

Mass (kg).

mu: Option<f64>

Gravitational parameter μ (m³/s²). If None, uses G × mass.

Implementations

impl Body

pub fn new(position: [f64; 3], velocity: [f64; 3], mass: f64) -> Self

Create a new body (gravity computed as G × mass).

pub fn with_mu( position: [f64; 3], velocity: [f64; 3], mass: f64, mu: f64, ) -> Self

Create a new body with an explicit gravitational parameter μ.

Use this when the standard μ value is known more precisely than G × M (e.g., μ_Earth = 3.986004418e14 m³/s²).

pub fn gravitational_parameter(&self) -> f64

Effective gravitational parameter (m³/s²).

pub fn kinetic_energy(&self) -> f64

Kinetic energy (J).

Trait Implementations

impl Clone for Body

fn clone(&self) -> Body

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Body

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Body

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Body

fn eq(&self, other: &Body) -> 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 Serialize for Body

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Body
