}

Drag table data structure

Fields

mach_values: Vec<f64>

cd_values: Vec<f64>

Implementations

impl DragTable

pub fn new(mach_values: Vec<f64>, cd_values: Vec<f64>) -> Self

Create a new drag table from mach and cd arrays

pub fn try_new( mach_values: Vec<f64>, cd_values: Vec<f64>, ) -> Result<Self, String>

Validated constructor for user-supplied drag decks. Enforces: equal-length axes, at least 2 points, strictly-ascending finite non-negative Mach, and finite positive Cd. Returns a descriptive, 1-based-row error string on failure (never panics).

pub fn from_csv_str(csv: &str) -> Result<Self, String>

Parse a user drag deck from CSV text: two columns mach,cd per line. Blank lines and lines starting with # are ignored; a single leading header row is skipped once, but only when its first column is not itself a valid number (e.g. mach,cd) — a first row whose first column does parse as a float (e.g. 0.5 or 0.5,O.2) is data, not a header, so a missing/invalid second column there is a hard error, not a silent skip. Any unparseable row is a hard error citing its 1-based line number. Values are validated via try_new.

pub fn from_file(path: impl AsRef<Path>) -> Result<Self, String>

Load and validate a user drag deck from a CSV file path.

pub fn interpolate(&self, mach: f64) -> f64

Interpolate drag coefficient for a Mach number, holding the nearest tabulated endpoint outside the table’s measured domain.

pub fn linear_interpolate(&self, mach: f64, idx: usize) -> f64

Linear interpolation between two points

pub fn cubic_interpolate(&self, mach: f64, idx: usize) -> f64

Cubic Hermite interpolation using four points and centered chord-slope tangents.
