Variants

DimensionMismatch

Fields

context: &'static str

expected: usize

got: usize

InvalidPoint(&'static str)

Singular(&'static str)

Unsupported(&'static str)

A manifold primitive has no implementation for this manifold and must not silently fall back to a wrong default (e.g. a curved-manifold VJP for which no closed form is wired up yet).

NonConvergence

An iterative geometry primitive exhausted or stalled without satisfying its analytic first-order certificate. The evidence is carried in the error so callers can distinguish non-convergence from invalid geometry and inspect the achieved residual rather than receiving a partial point.

Fields

context: &'static str

iterations: usize

residual: f64

tolerance: f64

FrechetMeanNotGloballyCertified

A Karcher solve reached first-order stationarity on a positively curved manifold, but the weighted support does not fit inside the analytic strongly-convex ball that certifies this stationary point as the unique global Fréchet mean. Returning the local basin would make the chart origin depend on initialization; callers must instead provide an explicit base point or better-localized data.

Fields

context: &'static str

stationarity_residual: f64

tolerance: f64

support_radius: f64

uniqueness_radius: f64
