# `Capstan.Snapshot.Meta`
[🔗](https://github.com/baselabs/capstan/blob/v1.3.1/lib/capstan/snapshot/meta.ex#L1)

The value-free metadata delivered alongside a snapshot chunk to
`c:Capstan.Sink.handle_snapshot/2`.

Carries only structural identity — the schema/table, the chunk sequence number, the
chunk's exact GTID position string `g` (captured under the brief per-chunk lock), and
whether this is the final chunk of the table. **No field holds a row value** (Rule 1),
so the whole struct is safe to inspect/log. `g` is a canonical GTID-set string
(`Capstan.Gtid` form), never a row value.

# `t`

```elixir
@type t() :: %Capstan.Snapshot.Meta{
  chunk_seq: non_neg_integer(),
  final_chunk?: boolean(),
  g: String.t(),
  schema: String.t(),
  table: String.t()
}
```
