this feature, in addition to the *what*)
-->
I have a bunch of parquet files that contain a binary column, here is the
schema:
```sql
CREATE EXTERNAL TABLE `buildings`(
`id` string,
`updateTime` string,
`version` int,
`names` string,
`level` int,
`height` double,
`geometry` binary
)
```
The `geometry` column is binary. Here is my struct:
```rust
#[derive(Deserialize)]
struct Building {
// omit for brevity ...
#[serde(default)]
geometry: Vec<u8>,
}
```
However, it failed to deserialize the parquet data with
`arrow::json::writer::record_batches_to_json_rows()`, here is the error:
```
Error: Json error: data type Binary not supported in nested map for json
writer
```
**Describe the solution you'd like**

`serde_json` should support deserialize binary to `Vec<u8>`.
