Struct TrajectoryPoint 

pub struct TrajectoryPoint {
    pub time: f64,
    pub position: Vector3<f64>,
    pub velocity_magnitude: f64,
    pub kinetic_energy: f64,
    pub drag_coefficient: Option<f64>,
}

Fields

time: f64

position: Vector3<f64>

velocity_magnitude: f64

kinetic_energy: f64

drag_coefficient: Option<f64>

The projectile’s own drag coefficient at this point (MBA-1423).

Filled in one pass after integration finishes, not at the sites that build this struct, so a solver family added later cannot silently omit it. None when sectional density is unavailable — see TrajectorySolver::effective_drag_coefficient for the definition and why this is the projectile’s Cd rather than the reference table’s.

Implementations

impl TrajectoryPoint

pub fn drag_coefficient_json_value( &self, with_drag_coefficient: bool, ) -> Option<f64>

The value --with-drag-coefficient emits for this point, or None when the JSON key must be ABSENT — flag off, or sectional density unknown (MBA-1427).

Host-compilable on purpose. The browser terminal’s emit site lives in src/wasm.rs, which is cfg(target_arch = "wasm32")-gated out of every native build — CI never executes a line of it. Keeping the gating rule here means a native test can pin the absent-not-null contract even though the surface that applies it only compiles for wasm.
