Enum RegularGridError 

#[non_exhaustive]
pub enum RegularGridError {
    TooFewPoints {
        found: usize,
    },
    DegeneratePointCloud,
    NoGridFound,
}

Failure modes of detect_regular_grid / RegularGridDetector::detect.

#[non_exhaustive]: future failure modes may be added. Each variant corresponds to a distinct early-exit in the detector.

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.

TooFewPoints

Fewer than four input points were supplied. Four is the minimum for a 2×2 seed quad, so no detection is possible.

Fields

found: usize

Number of points actually supplied.

DegeneratePointCloud

The point cloud is degenerate: collinear, pure noise, or otherwise carries no inferable square lattice. The grid-axis estimator could not extract a usable axis pair.

NoGridFound

The cloud has four or more points and a usable axis estimate, but no roughly-square parallelogram seed quad could be found.

Trait Implementations

impl Clone for RegularGridError

fn clone(&self) -> RegularGridError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegularGridError

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

Formats the value using the given formatter.

impl Display for RegularGridError

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

Formats the value using the given formatter.

impl Error for RegularGridError

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 RegularGridError

fn eq(&self, other: &RegularGridError) -> 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.
