QLDB examples using SDK for Rust

The following code examples show you how to perform actions and implement common scenarios by using the AWS SDK for Rust with QLDB.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

Actions

CreateLedger

The following code example shows how to use CreateLedger.

SDK for Rust

Note

There's more on GitHub. Find the complete example and learn how to set up and run in the AWS Code Examples Repository.

async fn make_ledger(client: &Client, ledger: &str) -> Result<(), Error> {
    let result = client
        .create_ledger()
        .name(ledger)
        .permissions_mode(PermissionsMode::AllowAll)
        .send()
        .await?;

    println!("ARN: {}", result.arn().unwrap());

    Ok(())
}

ListLedgers

The following code example shows how to use ListLedgers.

SDK for Rust

Note

There's more on GitHub. Find the complete example and learn how to set up and run in the AWS Code Examples Repository.

async fn show_ledgers(client: &QLDBClient) -> Result<(), Error> {
    let mut pages = client.list_ledgers().into_paginator().page_size(2).send();

    while let Some(page) = pages.next().await {
        println!("* {:?}", page); //Prints an entire page of ledgers.
        for ledger in page.unwrap().ledgers() {
            println!("* {:?}", ledger); //Prints the LedgerSummary of a single ledger.
        }
    }

    Ok(())
}
