/**
Create a snapshot test of the given database.
## Arguments
1. The identifier for the `Index`
2. The content of the index to snapshot. Available options are:
- `settings`
- `word_docids`
- `exact_word_docids`
- `word_prefix_docids`
- `exact_word_prefix_docids`
- `word_pair_proximity_docids`
- `word_prefix_pair_proximity_docids`
- `word_position_docids`
- `field_id_word_count_docids`
- `word_prefix_position_docids`
- `facet_id_f64_docids`
- `facet_id_string_docids`
- `documents_ids`
- `stop_words`
- `field_distribution`
- `fields_ids_map`
- `geo_faceted_documents_ids`
- `external_documents_ids`
- `number_faceted_documents_ids`
- `string_faceted_documents_ids`
- `words_fst`
- `words_prefixes_fst`
3. The identifier for the snapshot test (optional)
4. `@""` to write the snapshot inline (optional)
## Behaviour
The content of the database will be printed either inline or to the file system
at `test_directory/test_file.rs/test_name/db_name.snap`.
If the database is too large, then only the hash of the database will be saved, with
the name `db_name.hash.snap`. To *also* save the full content of the database anyway,
set the `MILLI_TEST_FULL_SNAPS` environment variable to `true`. The full snapshot will
be saved with the name `db_name.full.snap` but will not be saved to the git repository.
Running `cargo test` will check whether the old snapshot is identical to the
current one. If they are equal, the test passes. Otherwise, the test fails.
Use the command line `cargo insta` to approve or reject new snapshots.
## Example
```ignore
let index = TempIndex::new();
// basic usages
db_snap!(index, word_docids);
// named snapshot to avoid conflicts
db_snap!(index, word_docids, "some_identifier");
// write the snapshot inline
db_snap!(index, word_docids, @""); // will be autocompleted by running `cargo insta review`
// give a name to the inline snapshot
db_snap!(index, word_docids, "some_identifier", @"");
```
