Typed failure modes for calculate_lead.

Variants

InvalidInput(String)

Non-finite or out-of-domain input (negative speed, range ≤ 0, non-finite angle).

TargetOvertakesShooter

An inbound target closes to (or past) the shooter before intercept: the corrected range collapsed to ≤ 0 m.

Fields

corrected_range_m: f64

Convergence

The intercept-range iteration failed to reach RANGE_TOLERANCE_M within MAX_ITERATIONS (physically requires a radial speed comparable to the projectile’s remaining velocity).

Fields

iterations: u32

residual_m: f64

BeyondSolvedSpan

The intercept range moved beyond the distance the trajectory solve covered (an outbound target outrunning the solve’s headroom, or a solve that terminated early — e.g. ground impact — before reaching it).

Fields

corrected_range_m: f64

solved_span_m: f64

Solver(BallisticsError)

The underlying trajectory solve failed (invalid ballistic inputs, etc.).

Trait Implementations

impl Debug for LeadError

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

Formats the value using the given formatter.

impl Display for LeadError

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

Formats the value using the given formatter.

impl Error for LeadError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<BallisticsError> for LeadError

fn from(e: BallisticsError) -> Self

Converts to this type from the input type.
