Enum ConfiguredProjection 

pub enum ConfiguredProjection {
    Pca(PcaProjection),
    KernelPca(KernelPcaProjection),
    Laplacian(LaplacianEigenmapProjection),
}

A projection chosen at pipeline build time.

Implements Projection directly so EmbeddingIndex<ConfiguredProjection>, CategoryLayer::build_with_config, and every other Projection-generic API continues to work without changes.

Variants

Pca(PcaProjection)

KernelPca(KernelPcaProjection)

Laplacian(LaplacianEigenmapProjection)

Implementations

impl ConfiguredProjection

pub fn kind(&self) -> ProjectionKind

Which projection family is active.

pub fn explained_variance_ratio(&self) -> f64

Scalar projection-quality proxy, analogous to PCA’s explained variance ratio. For non-PCA variants this returns the kind’s native quality metric (Kernel PCA EVR, Laplacian connectivity ratio) — all bounded in [0, 1] so downstream EVR-adaptive thresholds stay well-defined.

pub fn as_pca(&self) -> Option<&PcaProjection>

Borrow the inner PcaProjection if that is the active variant.

pub fn as_kernel_pca(&self) -> Option<&KernelPcaProjection>

Borrow the inner KernelPcaProjection if that is the active variant.

pub fn as_laplacian(&self) -> Option<&LaplacianEigenmapProjection>

Borrow the inner LaplacianEigenmapProjection if that is the active variant.
