Struct Recorder 

pub struct Recorder { /* private fields */ }

Records chosen channels, one row per sample.

• With an interval, a row at every multiple of interval_s after launch that falls within the flight, and a row at every event (unless the last row already has that time).
• Without one, a row at the flight’s first step’s start and at every step’s end; events end steps, so they are among the rows.

A recorder keeps one flight: Recorder::clear it before recording another. It serializes its settings and rows for inspection; it is built with Recorder::new, not deserialized.

Implementations

impl Recorder

pub fn new( channels: Vec<Channel>, interval_s: Option<f64>, ) -> Result<Self, SimError>

A recorder of channels, sampling every interval_s seconds (None: every step’s end).

Errors

SimError::Domain for an interval that isn’t finite and positive; SimError::Unsupported for a channel listed twice, which would give two columns one name.

pub fn clear(&mut self)

Forgets the recorded rows, ready for another flight.

pub fn columns(&self) -> Vec<String>

The column names.

pub fn rows(&self) -> &[Vec<f64>]

The recorded rows.

Trait Implementations

impl Clone for Recorder

fn clone(&self) -> Recorder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Recorder

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

Formats the value using the given formatter.

impl Observer for Recorder

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 Recorder

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
