Enum GridError 

#[non_exhaustive]
pub enum GridError {
    UnsupportedCombination {
        task: GridTask,
        lattice: LatticeKind,
        evidence: EvidenceKind,
    },
    InsufficientEvidence,
    InconsistentInput(String),
    DegenerateGeometry,
}

User-facing failure modes for projective-grid tasks.

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.

UnsupportedCombination

The requested task/lattice/evidence combination is intentionally not implemented yet.

Fields

task: GridTask

Requested task.

lattice: LatticeKind

Requested lattice family.

evidence: EvidenceKind

Supplied evidence kind.

InsufficientEvidence

There is not enough evidence to run the requested task.

InconsistentInput(String)

Input slices disagree or contain duplicate/conflicting identifiers.

DegenerateGeometry

Geometry is degenerate, for example all model or image points are collinear.

Trait Implementations

impl Clone for GridError

fn clone(&self) -> GridError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GridError

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

Formats the value using the given formatter.

impl Display for GridError

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

Formats the value using the given formatter.

impl Eq for GridError

impl Error for GridError

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 GridError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
