Struct DragTable 

#[non_exhaustive]
pub struct DragTable {
    pub power_off: Table1D,
    pub power_on: Option<Table1D>,
    pub reference_diameter_m: Option<f64>,
}

Drag coefficient against Mach number, power-off and optionally power-on.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

power_off: Table1D

C_D0(M) with no motor thrusting.

power_on: Option<Table1D>

C_D0(M) while a motor thrusts; the power-off table applies when this is None.

reference_diameter_m: Option<f64>

The reference diameter the coefficients are on, m. When it differs from the rocket’s, crate::AeroModel::drag rescales by the ratio of the reference areas; None takes the coefficients as on the rocket’s reference area.

Implementations

impl DragTable

pub fn new(power_off: Table1D, power_on: Option<Table1D>) -> Self

A table with a power-off curve and an optional power-on curve, on the rocket’s reference area.

pub fn with_reference_diameter_m( self, diameter_m: f64, ) -> Result<Self, AeroError>

This table with its coefficients on a reference diameter of diameter_m, checked here as NormalForceTable::with_reference_diameter_m checks its own, so that a bad diameter is named when the table is made rather than at a flight’s first lookup (#79). A table built or read with the field set directly is still checked at its first lookup.

Errors

AeroError::Domain unless diameter_m is finite and positive.

pub fn from_csv( power_off: &str, power_on: Option<&str>, ) -> Result<Self, AeroError>

Reads a power-off curve and an optional power-on curve from two-column CSV text (parse_mach_csv with no column name).

Errors

As parse_mach_csv.

pub fn lookup(&self, mach: f64, thrusting: bool) -> Result<Lookup, AeroError>

C_D0 at mach on the table’s own reference area, from the power-on curve when thrusting and it exists.

Errors

AeroError::Domain for a negative or non-finite Mach number, and table errors.

Trait Implementations

impl Clone for DragTable

fn clone(&self) -> DragTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DragTable

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DragTable

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DragTable

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
