Module diff 

Structural diff between two JSON values — a port of the TS diff command’s collectDiffEntries / collectRecursiveDiff. Used to surface what normalize_board_model changed relative to the parsed board.yaml.

Rust serializes Option::None fields as null, whereas the TS model is sparse (absent keys are undefined). prune_nulls drops null-valued object entries so both sides diff the same shape the TS CLI does.

Structs

DiffEntry

One difference at a given path. before/after are omitted from JSON when None.

Enums

DiffKind

Classifies a single DiffEntry. Serializes lowercase (added/removed/changed).

Functions

collect_diff_entries

Collect every difference between before and after, sorted by path.

prune_nulls

Recursively remove null-valued object entries (object keys only; array elements are preserved so indices stay stable), mirroring how JS omits undefined object properties.
