Hello tutorial for the AWS SDK for Rust

In a terminal or console window, navigate to a location on your computer where you want to create the app.

Run the following command to create a hello_world directory and populate it with a skeleton Rust project:

$ cargo new hello_world --bin

Navigate into the hello_world directory and use the following command to add the required dependencies to the app:

$ cargo add aws-config aws-sdk-dynamodb tokio --features tokio/full

These dependencies include the SDK crates that provide configuration features and support for DynamoDB, including the tokio crate, which is used to implement asynchronous I/O operations.

Update main.rs in the src directory to contain the following code.

use aws_config::meta::region::RegionProviderChain;
use aws_config::BehaviorVersion;
use aws_sdk_dynamodb::{Client, Error};

/// Lists your DynamoDB tables in the default Region or us-east-1 if a default Region isn't set.
#[tokio::main]
async fn main() -> Result<(), Error> {
    let region_provider = RegionProviderChain::default_provider().or_else("us-east-1");
    let config = aws_config::defaults(BehaviorVersion::latest())
        .region(region_provider)
        .load()
        .await;
    let client = Client::new(&config);

    let resp = client.list_tables().send().await?;

    println!("Tables:");

    let names = resp.table_names();

    for name in names {
        println!("  {}", name);
    }

    println!();
    println!("Found {} tables", names.len());

    Ok(())
}

Run the program:

$ cargo run

You should see a list of your table names.
