Enum Rung 

pub enum Rung {
    IndexOnly,
    Regular,
    Rectilinear,
    Curvilinear,
    Fitted,
    ImplicitMesh,
    ExplicitMesh,
    Features,
}

The rung of the position ladder (design doc 02, section 3). Each rung stores strictly more than the one before.

Variants

IndexOnly

R0: index only.

Regular

R1: arithmetic from origin and step (affine).

Rectilinear

R2: outer product of 1D coordinate vectors.

Curvilinear

R3: one position per element, still (i, j) indexed.

Fitted

R3’: a fitted function of the index (GCP polynomial, RPC, TPS).

ImplicitMesh

R4: implicit mesh; arithmetic from a cell id (DGGS, L3 bins).

ExplicitMesh

R5: explicit mesh; stored positions plus connectivity.

Features

R6: features; a geometry per element.
