Enum PolylineFitExit 

pub enum PolylineFitExit {
    Converged,
    StationCeiling,
    InputExhausted,
    Stalled,
    Unrefined,
}

Why a polyline fit’s refinement stopped. Only PolylineFitExit::Converged means the tolerance was met; every other variant is a BUDGET exit whose deviation was measured on the curve actually returned.

Variants

Converged

A measured rung came in at or under the tolerance.

StationCeiling

MAX_FIT_STATIONS bound with the tolerance unmet and the input still holding stations the ladder never used.

InputExhausted

Every station the input offers is an interpolation station and the tolerance is still unmet. More points cannot help; a different lane, a finer march or a looser bar can.

Stalled

A doubling failed to improve the deviation by STALL_FACTOR, so the input rather than the station count is what binds. The better of the two curves is returned.

Unrefined

No refinement was attempted: fit_polyline_at fits exactly one rung, and BREP_POLYLINE_FIT_REFINE=0 makes fit_polyline do the same.
