Amazon's QLDB Driver

Driver for Amazon's QLDB Database implemented in pure rust.

Example

```rust,no_run use qldb::QLDBClient; let client = QLDBClient::default("rust-crate-test").await?;

let mut map = HashMap::new(); map.insert( "testcolumn".tostring(), IonValue::String("testvalue".tostring()), ); IonValue::Struct(map)

client .transactionwithin(|client| { let testtable = test_table.clone(); async move {

        let _ = client
            .query(&format!("INSERT INTO {} VALUE ?", test_table), &[get_value_to_insert()])
            .await;

        client.rollback().await
    }
})
.await?;

```

Test

For tests you will need to have some AWS credentials in your PC (as env variables or in ~/.aws/credentials). There needs to be a QLDB database with the name "rust-crate-test" in the aws account. The tests need to be run sequentially, so in order to run the tests please run the following command:

sh RUST_TEST_THREADS=1 cargo test
