# Blob

`Blob` is represented as one of:

- `&[u8]`,
- `Vec<u8>`,
- `bytes::Bytes`,
- `[u8; N]` (only serialization supported).

```rust
use futures::TryStreamExt;

// Insert some blob into the table as a Vec<u8>
// We can insert it by reference to not move the whole blob
let to_insert: Vec<u8> = vec![1, 2, 3, 4, 5];
session
    .query_unpaged("INSERT INTO keyspace.table (a) VALUES(?)", (&to_insert,))
    .await?;

// Read blobs from the table
let mut stream = session.query_iter("SELECT a FROM keyspace.table", &[])
    .await?
    .rows_stream::<(Vec<u8>,)>()?;
while let Some((blob_value,)) = stream.try_next().await? {
    println!("{:?}", blob_value);
}
```
