Struct SquareGridStats 

#[non_exhaustive]
pub struct SquareGridStats {
    pub seed: Option<[usize; 4]>,
    pub grown: usize,
    pub extension: Option<ExtensionStats>,
    pub fill: Option<FillStats>,
    pub validation: Option<ValidationResult>,
    pub dropped_by_validation: usize,
}

Per-stage counters returned alongside SquareGridDetection.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

seed: Option<[usize; 4]>

Corner indices of the chosen seed quad, in [A, B, C, D] order. None indicates seed finding failed (in which case detect_square_grid returns None and this struct is not produced).

grown: usize

Number of corners attached during the BFS grow stage, excluding the four seed corners.

extension: Option<ExtensionStats>

Boundary-extension diagnostics. None when extension was disabled via SquareGridParams::extension = None.

fill: Option<FillStats>

Hole-fill diagnostics. None when fill was disabled or the labelled set was empty before fill ran.

validation: Option<ValidationResult>

Validation outcome. None when validation was disabled.

dropped_by_validation: usize

Number of corners dropped from labelled because validation flagged them. Always 0 when validation was disabled.
