Module cell

Expand description

Cells: frozen, immutable artifacts produced by freezing a CellBuilder.

Invariants held after CellBuilder::freeze:

content_hash is a deterministic blake3 of the canonical encoding. Same shapes/instances/ports/properties → same hash, byte-stable across runs and platforms.
local_bbox is the union of shape bboxes (instance subtrees not included).
shapes keys are sorted by LayerIndex; per-layer shape order is the insertion order from the builder, but hashing sorts canonically.
instances, ports, properties are stored in insertion order; hashing sorts canonically. UI/IO consumers may sort if they care.

Mutation after freeze is impossible — there is no public &mut Cell.
