Struct Keplerian 

pub struct Keplerian { /* private fields */ }

A set of Keplerian orbital elements.

Implementations

impl Keplerian

pub fn new( semi_major_axis: SemiMajorAxis, eccentricity: Eccentricity, inclination: Inclination, longitude_of_ascending_node: LongitudeOfAscendingNode, argument_of_periapsis: ArgumentOfPeriapsis, true_anomaly: TrueAnomaly, ) -> Self

Creates a new set of Keplerian elements from pre-validated components.

pub fn builder() -> KeplerianBuilder

Returns a new KeplerianBuilder.

pub fn semi_major_axis(&self) -> SemiMajorAxis

Returns the semi-major axis.

pub fn eccentricity(&self) -> Eccentricity

Returns the eccentricity.

pub fn inclination(&self) -> Inclination

Returns the inclination.

pub fn longitude_of_ascending_node(&self) -> LongitudeOfAscendingNode

Returns the longitude of ascending node.

pub fn argument_of_periapsis(&self) -> ArgumentOfPeriapsis

Returns the argument of periapsis.

pub fn true_anomaly(&self) -> TrueAnomaly

Returns the true anomaly.

pub fn semi_parameter(&self) -> Distance

Returns the semi-parameter (semi-latus rectum) of the orbit.

pub fn to_perifocal(&self, grav_param: GravitationalParameter) -> (DVec3, DVec3)

Converts the orbital elements to position and velocity in the perifocal frame.

pub fn to_cartesian(&self, grav_param: GravitationalParameter) -> Cartesian

Converts the orbital elements to a Cartesian state vector.

pub fn orbital_period( &self, grav_param: GravitationalParameter, ) -> Option<TimeDelta>

Returns the orbital period, or None for non-elliptic orbits.

pub fn iter_trace( &self, grav_param: GravitationalParameter, n: usize, ) -> impl Iterator<Item = Cartesian>

Returns an iterator over n Cartesian positions equally spaced around the orbit.

pub fn trace( &self, grav_param: GravitationalParameter, n: usize, ) -> Option<Vec<Cartesian>>

Returns n Cartesian positions equally spaced around the orbit, or None for non-elliptic orbits.

Trait Implementations

impl ApproxEq for Keplerian

fn approx_eq(&self, rhs: &Self, atol: f64, rtol: f64) -> ApproxEqResults

Compares self with rhs for approximate equality.

impl Clone for Keplerian

fn clone(&self) -> Keplerian

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Keplerian

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

Formats the value using the given formatter.

impl PartialEq for Keplerian

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