These examples demonstrate how to perform several operations using the developer preview version of the AWS SDK for Rust.
- We recommend that you grant this code least privilege, or at most the minimum permissions required to perform the task. For more information, see Grant Least Privilege in the AWS Identity and Access Management User Guide.
- This code has not been tested in all AWS Regions. Some AWS services are available only in specific Regions.
- Running this code might result in charges to your AWS account.
The AWS SDK for Rust uses Environment Variables to configure some of its behavior. These variables are documented in the AWS SDK for Rust Developer Guide. Some common and useful variables are described here for easy reference.
The following environment variables are a subset of the variables used by the AWS Command Line Interface (AWS CLI) that are supported by the AWS SDK for Rust. See Configuring the AWS CLI - Environment Variables for more details on these variables.
- AWS_REGION (AWS_DEFAULT_REGION) specifies the AWS Region to send requests to.
- AWS_PROFILE specifies the name of the AWS CLI profile with the credentials and options to use. This can be the name of a profile stored in a credentials or config file, or the value default to use the default profile.
- AWS_ACCESS_KEY_ID specifies an AWS access key associated with an IAM user or role.
- AWS_SECRET_ACCESS_KEY (SECRET_ACCESS_KEY) specifies the secret key associated with the access key. This is essentially the "password" for the access key.
The following environment variables are specific to using the AWS SDK for Rust running in Amazon Elastic Container Service (Amazon ECS). See AWS SDKs and Tools - Container Credentials for more information.
- AWS_CONTAINER_CREDENTIALS_FULL_URI specifies the full HTTP URL endpoint for the SDK to use when making a request for credentials.
- AWS_CONTAINER_CREDENTIALS_RELATIVE_URI specifies the relative HTTP URL endpoint for the SDK to use when making a request for credentials.
- AWS_CONTAINER_AUTHORIZATION_TOKEN specifies the Authorization header on HTTP requests.
The following environment variables specify how Instance Metadata Service (IMDS) provides data about your instance when using the AWS SDK for Rust running in Amazon EC2. See AWS SDKs and Tools - IMDS Credentials for more information.
- AWS_EC2_METADATA_DISABLED specifies whether or not to attempt to use IMDS to obtain credentials.
- AWS_EC2_METADATA_SERVICE_ENDPOINT specifies the endpoint for IMDS.
- AWS_EC2_METADATA_SERVICE_ENDPOINT_MODE specifies whether to access IMDS using IPv4 or IPv6.
The following environment variables are specific to the AWS SDK for Rust.
- AWS_SDK_UA_APP_ID specifies an additional app name that will be present in the User-Agent header for every SDK request.
You must have an AWS account, and have configured your default credentials and AWS Region as described in Getting started with the AWS SDK for Rust.
See the individual readme files in each service directory for information about specific code examples for that service.
This example code will soon be available in a container image hosted on Amazon Elastic Container Registry (ECR). This image will be pre-loaded with all Rust examples with dependencies pre-resolved, allowing you to explore these examples in an isolated environment.
To propose a new code example to the AWS documentation team, see CONTRIBUTING.md. The team prefers to create code examples that show broad scenarios rather than individual API calls.
