Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidOptics(String),
    InvalidFootprint {
        provenance: String,
        reason: String,
    },
    FootprintEpochMismatch,
    AntipodalGeometry,
    ProjectionFailed(String),
    EmptyFootprintSet,
    DuplicateFootprintProvenance(String),
    InvalidCoverageBand(String),
    InvalidRotationSearch(String),
    InvalidEllipse(String),
    InvalidObjectGeometry(String),
}

Everything that can go wrong constructing target-match values.

Example

use target_match::{Error, Field, Optics};

let err = Field::from_optics(Optics {
    focal_mm: 0.0, pixel_um: (3.76, 3.76), binning: (1, 1), pixels: (6248, 4176),
})
.unwrap_err();
assert!(matches!(err, Error::InvalidOptics(_)));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidOptics(String)

Optics or field inputs were non-positive, non-finite, or insufficient to derive a field of view.

InvalidFootprint

An ordered captured boundary is degenerate, self-intersecting, or does not contain its declared centre.

Fields

provenance: String

Caller-supplied evidence identity.

reason: String

Validation failure.

FootprintEpochMismatch

Compared geometry uses different coordinate epochs.

AntipodalGeometry

A common tangent anchor cannot be selected for antipodal geometry.

ProjectionFailed(String)

A point is at or beyond the selected gnomonic projection horizon.

EmptyFootprintSet

A footprint union requires at least one input.

DuplicateFootprintProvenance(String)

Per-panel evidence requires unique provenance identities.

InvalidCoverageBand(String)

A normalized coverage band is non-finite, reversed, or outside [0, 1].

InvalidRotationSearch(String)

A residual-rotation search domain or resolution is invalid.

InvalidEllipse(String)

An ellipse has invalid axes, orientation, or sampling resolution.

InvalidObjectGeometry(String)

Caller-supplied object geometry cannot produce a positive planar area.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for Error
