Enum Step 

pub enum Step {
    Static(Iso3),
    Dyn {
        edge: EdgeId,
        inverted: bool,
    },
}

One step of a compiled plan.

Not #[non_exhaustive], for InterpPolicy’s reason rather than by oversight. The only thing a consumer does with Plan::steps is classify each step — “which edges does this plan sample?” is what tf_tree_bench::workload, tf_tree_py::offline and the derivative tests all ask — and a _ => arm answers no for a step kind it has never seen. That under-counts silently, where a compile error names the file to fix.

Variants

Static(Iso3)

A constant transform composed directly (a folded static edge or a run of them). Pre-inverted at compile time when it came from an inverted edge.

Dyn

A dynamic edge to be sampled at evaluation time. inverted composes the inverse of the sampled pose (acc.mul_inv(p)); otherwise acc * p.

Fields

edge: EdgeId

The edge to sample.

inverted: bool

Whether to compose the sampled pose inverted.
