# aws-sdk-greengrass AWS IoT Greengrass seamlessly extends AWS onto physical devices so they can act locally on the data they generate, while still using the cloud for management, analytics, and durable storage. AWS IoT Greengrass ensures your devices can respond quickly to local events and operate with intermittent connectivity. AWS IoT Greengrass minimizes the cost of transmitting data to the cloud by allowing you to author AWS Lambda functions that execute locally. ## Getting Started > Examples are available for many services and operations, check out the > [examples folder in GitHub](https://github.com/awslabs/aws-sdk-rust/tree/main/examples). The SDK provides one crate per AWS service. You must add [Tokio](https://crates.io/crates/tokio) as a dependency within your Rust project to execute asynchronous code. To add `aws-sdk-greengrass` to your project, add the following to your **Cargo.toml** file: ```toml [dependencies] aws-config = { version = "1.1.7", features = ["behavior-version-latest"] } aws-sdk-greengrass = "1.49.0" tokio = { version = "1", features = ["full"] } ``` Then in code, a client can be created with the following: ```rust,no_run use aws_sdk_greengrass as greengrass; #[::tokio::main] async fn main() -> Result<(), greengrass::Error> { let config = aws_config::load_from_env().await; let client = aws_sdk_greengrass::Client::new(&config); // ... make some calls with the client Ok(()) } ``` See the [client documentation](https://docs.rs/aws-sdk-greengrass/latest/aws_sdk_greengrass/client/struct.Client.html) for information on what calls can be made, and the inputs and outputs for each of those calls. ## Using the SDK Until the SDK is released, we will be adding information about using the SDK to the [Developer Guide](https://docs.aws.amazon.com/sdk-for-rust/latest/dg/welcome.html). Feel free to suggest additional sections for the guide by opening an issue and describing what you are trying to do. ## Getting Help * [GitHub discussions](https://github.com/awslabs/aws-sdk-rust/discussions) - For ideas, RFCs & general questions * [GitHub issues](https://github.com/awslabs/aws-sdk-rust/issues/new/choose) - For bug reports & feature requests * [Generated Docs (latest version)](https://awslabs.github.io/aws-sdk-rust/) * [Usage examples](https://github.com/awslabs/aws-sdk-rust/tree/main/examples) ## License This project is licensed under the Apache-2.0 License.
