## Example

### Via Builder

```rust,no_run
use opendal_core::Operator;
use opendal_core::Result;
use opendal_service_sqlite::Sqlite;

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Sqlite::default()
        .root("/")
        .connection_string("file//abc.db")
        .table("your_table")
        // key field type in the table should be compatible with Rust's &str like text
        .key_field("key")
        // value field type in the table should be compatible with Rust's Vec<u8> like bytea
        .value_field("value");

    let op = Operator::new(builder)?.finish();
    Ok(())
