Rusoto is an AWS SDK for Rust

Maintenance status

⚠️ Rusoto is in maintenance mode. ⚠️

The current maintainers only have the bandwidth to review dependency bumps and obvious bugfixes. Our bandwidth for reviewing new features is extremely limited.

While you are welcome to submit PRs that implement new features or refactor existing code, they are unlikely to be merged unless we can find more active maintainers.

Please see Meta: future of Rusoto (#1651) for details.


Rusoto is available on crates.io. To use Rusoto in your Rust program built with Cargo, add it as a dependency and rusoto_$SERVICENAME for any supported AWS service you want to use.

For example, to include only S3 and SQS:

rusoto_core = "0.48.0"
rusoto_sqs = "0.48.0"
rusoto_s3 = "0.48.0"

Migration notes

Breaking changes and migration details are documented at https://rusoto.org/migrations.html.

Note that from v0.43.0 onward, Rusoto uses Rust's std::future::Future, and the Tokio 0.2 ecosystem. From v0.46.0 onward, Rusoto uses the Tokio 1.0 ecosystem.


Rusoto has a crate for each AWS service, containing Rust types for that service's API. A full list of these services can be found here. All other public types are reexported to the crate root. Consult the rustdoc documentation for full details by running cargo doc or visiting the online documentation for the latest crates.io release.

A simple example of using Rusoto's DynamoDB API to list the names of all tables in a database:

use rusoto_core::Region;
use rusoto_dynamodb::{DynamoDb, DynamoDbClient, ListTablesInput};

async fn main() {
    let client = DynamoDbClient::new(Region::UsEast1);
    let list_tables_input: ListTablesInput = Default::default();

    match client.list_tables(list_tables_input).await {
        Ok(output) => match output.table_names {
            Some(table_name_list) => {
                println!("Tables in database:");

                for table_name in table_name_list {
                    println!("{}", table_name);
            None => println!("No tables in database!"),
        Err(error) => {
            println!("Error: {:?}", error);

Semantic versioning

Rusoto complies with semantic versioning 2.0.0. Until reaching 1.0.0 the API is to be considered unstable. See Cargo.toml or rusoto on crates.io for current version.


Information on release schedules and procedures are in RELEASING.


Discussions take place on the Rusoto Discord channel.

See CONTRIBUTING for more information.

Supported OSs, Rust versions and non-AWS projects

Linux, macOS and Windows are supported and tested via GitHub actions.

Rust stable, beta and nightly are supported.

Rusoto's primary aim is to be used with AWS. Other projects that provide AWS-like APIs, such as Ceph, Minio, Yandex Object Storage, etc... are not a focus at this time. PRs to fix issues with Rusoto and AWS-like APIs are welcome but generally won't be created by Rusoto maintainers.


Rusoto is distributed under the terms of the MIT license.
