}

Everything the wind fit needs: the observed misses plus the load, rifle, atmosphere and the opt-in earth frame (MBA-1392).

Imperial units for the load/atmosphere fields, matching the truing core’s historical internal convention; the observations themselves are SI. Unlike the drop-based truing commands this carries a KNOWN muzzle velocity — wind is the unknown being fitted, so velocity is an input, not an output.

Fields

observations: Vec<WindObservation>

One or more observed horizontal misses. Ranges must be distinct.

muzzle_velocity_fps: f64

Known muzzle velocity, feet/second (true up first with true-velocity if unsure).

bc: f64

Scalar ballistic coefficient for drag_model.

drag_model: DragModelArg

mass_gr: f64

Bullet mass in grains.

diameter_in: f64

Bullet diameter in inches.

zero_distance_yd: f64

Zero distance in yards.

sight_height_in: f64

Sight height over bore in inches.

temperature_f: f64

Ambient temperature in degrees Fahrenheit.

pressure_inhg: f64

Station pressure in inches of mercury.

humidity_pct: f64

Relative humidity in percent (0 through 100).

altitude_ft: f64

Altitude in feet.

twist: TruingTwist

Barrel twist. REQUIRED: spin drift is a lateral effect of the same order as a light wind at long range, so without it the fit would silently report spin drift as wind.

earth: Option<TruingEarthFrame>

Latitude + shot azimuth. None leaves Coriolis unmodelled and absorbed into the solved wind (the report names it as unsubtracted).

called_crosswind_mph: Option<f64>

The wind the shooter CALLED, mph, in the same signed convention as the solved value. Some adds a wind-call correction factor (solved / called) to the report.

Implementations

impl WindTruingRequest

pub fn validate(&self) -> Result<(), String>

Validate the whole request before any (expensive) trajectory work begins.

Mirrors crate::truing::TruingModelInputsV1::validate plus the observation-set rules from crate::truing::validate_truing_observations: finite positive ranges, finite misses, no duplicate ranges. Sigmas are all-or-none — a half-weighted set would silently mix an inverse-variance mean with unit weights.

Trait Implementations

impl Clone for WindTruingRequest

fn clone(&self) -> WindTruingRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindTruingRequest

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

Formats the value using the given formatter.
