Struct MotorFile 

pub struct MotorFile {
    pub manufacturer: String,
    pub designation: String,
    pub diameter_mm: f64,
    pub length_mm: f64,
    pub delays: String,
    pub propellant_mass_kg: f64,
    pub total_mass_kg: f64,
    pub curve: ThrustCurve,
}

A parsed RASP motor file (the .eng format used by thrustcurve.org and OpenRocket): a header line of manufacturer, designation, diameter, length, delays and masses, then time/thrust samples.

Fields

manufacturer: String

Manufacturer code, e.g. “AeroTech” or “Estes”.

designation: String

Motor designation, e.g. “C6” or “D12”.

diameter_mm: f64

Motor diameter in millimetres.

length_mm: f64

Motor length in millimetres.

delays: String

Delay token from the file (“0”, “4”, “P” for plugged, …).

propellant_mass_kg: f64

Propellant mass in kilograms.

total_mass_kg: f64

Loaded motor mass (casing included) in kilograms.

curve: ThrustCurve

The parsed thrust curve.

Implementations

impl MotorFile

pub fn parse(text: &str) -> Result<Self>

Parse RASP text. ; starts a comment, blank lines are ignored, and the first non-comment line must be the header.

pub fn from_path(path: impl AsRef<Path>) -> Result<Self>

Read and parse a .eng file from disk (native builds).

pub fn motor(&self, ignition_time_s: f64) -> Result<Motor>

Build a scheduled motor from the parsed curve and propellant mass.

Trait Implementations

impl Clone for MotorFile

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MotorFile

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

Formats the value using the given formatter.
