AshUi.Patch.Runtime (ash_ui v0.1.0)

Change derivation over a compiled AshUi.Patch.Table.

The patching protocol is the live host's own: the compiled skeleton supplies statics, evaluator closures supply dynamics, and the ONLY thing this module contributes is the changed-address set — which dynamics may return a value instead of nil under change tracking. The live host's diff engine and client own every DOM decision; there is no parallel op vocabulary, no slot-value store, no tree.

diff/2 compares attributes AND loaded relationships, calculations, and aggregates — relationship-as-read reactivity means a reloaded relationship with unchanged attributes must still invalidate the slots that read it. A field that is %Ash.NotLoaded{} on both sides is unchanged; loaded on one side only is changed (the truth moved or is unknown — invalidate).

Summary

Functions

changed_addresses(resource_or_table, old_record, new_record)

The changed slot addresses between two records, straight from the propagation index — the gate the live host needs to build a differential render. :all when the before-image is missing or the resources differ.

diff(old, new)

Changed field names between two records of the same resource.

Functions

changed_addresses(resource_or_table, old_record, new_record)

diff(old, new)

@spec diff(struct(), struct()) :: %{fields: [atom()]}
