# `Statifier.Interpreter.Datamodel.Write`
[🔗](https://github.com/riddler/statifier-ex/blob/v2.0.0/lib/statifier/interpreter/datamodel/write.ex#L1)

What `Statifier.Interpreter.Datamodel.write_location/4` wrote - a report of
a write that already happened, never an instruction to perform one. `path`
is the resolved `Predicator.ContextLocation.location_path()`, `new_value` is
what was written, and `prior_value` is what stood at that full path
immediately before the write - `:undefined` when nothing did, per
ADR-0037's single spelling for an unbound value. This does conflate "the
path was absent" with "the path held `:undefined`" already; that is
accepted, since `prior_value` exists for diffing and undo, never for
reconstruction.

# `t`

```elixir
@type t() :: %Statifier.Interpreter.Datamodel.Write{
  new_value: term(),
  path: Predicator.ContextLocation.location_path(),
  prior_value: term()
}
```
