One motor in a .eng file.

Fields

comments: Vec<String>

Comments before the header, without the leading ;.

name: String

The motor’s name, such as F32 or 1266-J760-WT-19A.

diameter_mm: f64

Casing diameter, mm.

length_mm: f64

Casing length, mm.

delays: String

The delay string as written, such as 6-10-14 or P; see EngEntry::delays.

propellant_mass_kg: f64

Propellant mass, kg.

total_mass_kg: f64

Loaded motor mass, kg.

manufacturer: String

Manufacturer abbreviation, such as AT or Cesaroni_Technology.

points: Vec<(f64, f64)>

The points as listed: (time s, thrust N).

Implementations

impl EngEntry

pub fn delays(&self) -> DelayList

The delay settings read from EngEntry::delays.

pub fn thrust_curve(&self) -> Result<ThrustCurve, MotorError>

The entry’s thrust curve, starting from the implicit (0, 0) when the first point is after ignition.

Errors

As ThrustCurve::new: negative thrust, decreasing time, or no thrust.

Trait Implementations

impl Clone for EngEntry

fn clone(&self) -> EngEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EngEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EngEntry

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
