Enum RefineStatus 

#[non_exhaustive]
pub enum RefineStatus {
    Accepted,
    Rejected,
    OutOfBounds,
    IllConditioned,
}

Status of a refinement attempt.

A refiner returns one of these variants to indicate whether it produced a usable subpixel location and, if not, why it did not.

• Accepted — refinement converged; use RefineResult::x and y.
• Rejected — the refiner ran but the result did not pass an acceptance criterion (e.g. the computed displacement exceeded ForstnerConfig::max_offset). Fall back to the original seed or skip this candidate.
• OutOfBounds — the seed is too close to the image border for the refiner’s patch window. The seed coordinates in RefineResult are unchanged from the input.
• IllConditioned — the patch does not contain enough structure for the refiner to produce a reliable estimate (e.g. too-flat gradient for Förstner, or a degenerate Hessian for saddle-point). The seed coordinates are unchanged.

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.

Accepted

Refinement converged; the result’s x/y are usable.

Rejected

The refiner ran but the result failed its acceptance criterion.

OutOfBounds

The seed is too close to the image border for the refiner’s patch window.

IllConditioned

The patch lacks enough structure for a reliable estimate.

Trait Implementations

impl Clone for RefineStatus

fn clone(&self) -> RefineStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RefineStatus

impl Debug for RefineStatus

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

Formats the value using the given formatter.

impl Eq for RefineStatus

impl PartialEq for RefineStatus

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