Struct State 

pub struct State {
    pub position_enu_m: DVec3,
    pub velocity_enu_m_s: DVec3,
    pub attitude: DQuat,
    pub body_rate_rad_s: DVec3,
}

A rigid body’s state in the launch frame L (docs/physics/frames.md).

The reference point is the body origin, the nose tip (the decision record on the design tree, ADR-007), which is fixed in the body; the center of mass moves relative to it as propellant burns. As an array the order is position, velocity, attitude (w, x, y, z) and body rates.

Fields

position_enu_m: DVec3

The nose tip’s position in L, m.

velocity_enu_m_s: DVec3

The nose tip’s velocity relative to L, m/s.

attitude: DQuat

The attitude, body to launch frame. The integrated quaternion’s norm drifts slightly; every use normalizes it.

body_rate_rad_s: DVec3

The body’s angular velocity relative to L, in body axes, rad/s.

Implementations

impl State

pub fn to_array(&self) -> [f64; 13]

The state as the integrator’s array.

pub fn from_array(y: &[f64; 13]) -> Self

The state from the integrator’s array.

pub fn unit_attitude(&self) -> DQuat

The attitude scaled to unit length.

pub fn point_enu_m(&self, body_m: DVec3) -> DVec3

A point given in body axes (m from the nose tip), in L.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for State

impl Debug for State

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for State

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for State

fn eq(&self, other: &State) -> 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 State

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
