Enum WorkerDecision 

pub enum WorkerDecision {
    Clear,
    CacheHit,
    Recomputed,
}

Recompute decision the worker takes on a wake. Visible for testing; the production loop calls recompute directly.

As of D.4.d.2.1.c the worker iterates rs.cells.panes and produces one decision per pane; the aggregate decision returned to run is the highest-precedence one across panes (Recomputed > Clear > CacheHit).

Variants

Clear

Pane had no document snapshot (transient race during buffer close, or non-Document leaf — though the publisher already filters those out). Worker cleared that pane’s matrix (or noted it was already empty).

CacheHit

Fingerprint of (providers × versions, source_line_count) matches the previously observed fingerprint for this pane’s buffer. No new matrix published; renderer reads the existing one.

Recomputed

Fingerprint changed. Worker polled collect() on every registered provider for the pane’s buffer, built a fresh VirtualRowMatrix, and stored it via pane.virtual_rows_matrix.
