Struct FlightMetrics 

pub struct FlightMetrics { /* private fields */ }

Watches a flight and keeps its peaks, and its stability from the rail exit to apogee or the first deployment.

Each step is sampled at its start, middle and end. When the parabola through the three has its top inside the step, a golden-section search on the dense output finds the peak there; the largest of what it finds and the three samples is kept. The least margins are found the same way, with the parabola turned over. Thrust-curve knots and events end steps, so a thrust spike’s peak is a step’s end. Nothing is kept on the pad.

A watcher keeps one flight: FlightMetrics::clear it before watching another, and FlightMetrics::summary refuses a flight whose steps it didn’t all see, once each. Like crate::Recorder, it serializes what it holds for inspection and is built with FlightMetrics::new, not deserialized.

Implementations

impl FlightMetrics

pub fn new() -> Self

A watcher with nothing seen.

pub fn clear(&mut self)

Forgets what it saw, ready for another flight.

pub fn stability(&self) -> &[Stability]

The stability from the rail exit (or the start of a flight begun in the air) to apogee or the first deployment, whichever comes first: at the rail exit and at every step’s end, in time order. A powered separation adds the sustainer’s own entry at the split, after the stack’s and at the same time, so the watcher needs the flight’s events as well as its steps.

pub fn summary( &self, result: &FlightResult, environment: &Environment, ) -> Result<FlightSummary, SimError>

The summary of result, the flight this watched, flown in environment.

Errors

SimError::Domain if it didn’t see each of result’s accepted steps once, or its last step ended after result did (it watched another flight, or wasn’t cleared between two); SimError::Core if a landing has no geodetic coordinates.

Trait Implementations

impl Clone for FlightMetrics

fn clone(&self) -> FlightMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlightMetrics

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

Formats the value using the given formatter.

impl Default for FlightMetrics

fn default() -> FlightMetrics

Returns the “default value” for a type.

impl Observer for FlightMetrics

fn step(&mut self, step: &dyn FlightStep) -> Result<(), SimError>

Sees every accepted integration step, in order.

fn event(&mut self, event: &FlightEvent)

Sees every flight event as it is recorded.

impl PartialEq for FlightMetrics

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
