Enum ReticleError 

pub enum ReticleError {
    NonPositiveMagnification {
        magnification: f64,
    },
    NonPositiveReferenceMagnification {
        reference_magnification: f64,
    },
    NoMarks,
    TooManyMarks {
        count: usize,

    NonFiniteMark {
        index: usize,
    },
    NonFiniteHold {
        drop_mil: f64,
        wind_mil: f64,
    },
    InvalidGeneratorParameter {
        parameter: &'static str,
        value: f64,
        rule: &'static str,
    },
}

Why a reticle operation was rejected. Typed rather than stringly, so front ends can render their own wording and the FFI can map to a code.

Variants

NonPositiveMagnification

magnification was not finite and strictly positive. Checked on EVERY focal plane — an FFP hold does not depend on it, but zero magnification is not a physical optic and silently accepting it would mask a caller bug.

Fields

magnification: f64

NonPositiveReferenceMagnification

An SFP reticle carried a non-finite or non-positive ReticleDescription::reference_magnification, which its subtension scaling divides by conceptually and multiplies by literally.

Fields

reference_magnification: f64

NoMarks

The description carried no marks. A hold point has nothing to be near.

TooManyMarks

The description carried more than MAX_RETICLE_MARKS marks.

Fields

count: usize

max: usize

NonFiniteMark

A mark’s coordinates were not finite.

Fields

index: usize

NonFiniteHold

The supplied firing solution (drop_mil / wind_mil) was not finite.

Fields

drop_mil: f64

wind_mil: f64

InvalidGeneratorParameter

A generator parameter violated its rule.

Fields

parameter: &'static str

value: f64

rule: &'static str

Trait Implementations

impl Clone for ReticleError

fn clone(&self) -> ReticleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReticleError

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

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
