Struct Client

pub struct Client { /* private fields */ }

Client for Amazon Aurora DSQL

Client for invoking operations on Amazon Aurora DSQL. Each operation on Amazon Aurora DSQL is a method on this this struct. .send() MUST be invoked on the generated operations to dispatch the request to the service.

Constructing a Client

A Config is required to construct a client. For most use cases, the aws-config crate should be used to automatically resolve this config using aws_config::load_from_env(), since this will resolve an SdkConfig which can be shared across multiple different AWS SDK clients. This config resolution process can be customized by calling aws_config::from_env() instead, which returns a ConfigLoader that uses the builder pattern to customize the default config.

In the simplest case, creating a client looks as follows:

let config = aws_config::load_from_env().await;
let client = aws_sdk_dsql::Client::new(&config);

Occasionally, SDKs may have additional service-specific values that can be set on the Config that is absent from SdkConfig, or slightly different settings for a specific client may be desired. The Builder struct implements From<&SdkConfig>, so setting these specific settings can be done as follows:

let sdk_config = ::aws_config::load_from_env().await;
let config = aws_sdk_dsql::config::Builder::from(&sdk_config)
    .some_service_specific_setting("value")
    .build();

See the aws-config docs and Config for more information on customizing configuration.

Note: Client construction is expensive due to connection thread pool initialization, and should be done once at application start-up.

Using the Client

A client has a function for every operation that can be performed by the service. For example, the CreateCluster operation has a Client::create_cluster, function which returns a builder for that operation. The fluent builder ultimately has a send() function that returns an async future that returns a result, as illustrated below:

let result = client.create_cluster()
    .kms_encryption_key("example")
    .send()
    .await;

The underlying HTTP requests that get made by this can be modified with the customize_operation function on the fluent builder. See the customize module for more information.

Waiters

This client provides wait_until methods behind the Waiters trait. To use them, simply import the trait, and then call one of the wait_until methods. This will return a waiter fluent builder that takes various parameters, which are documented on the builder type. Once parameters have been provided, the wait method can be called to initiate waiting.

For example, if there was a wait_until_thing method, it could look like:

let result = client.wait_until_thing()
    .thing_id("someId")
    .wait(Duration::from_secs(120))
    .await;

Implementations

impl Client

pub fn create_cluster(&self) -> CreateClusterFluentBuilder

Constructs a fluent builder for the CreateCluster operation.

• The fluent builder is configurable:
  • deletion_protection_enabled(bool) / set_deletion_protection_enabled(Option<bool>):
    required: false
    

    If enabled, you can’t delete your cluster. You must first disable this property before you can delete your cluster.

    
    
  • kms_encryption_key(impl Into<String>) / set_kms_encryption_key(Option<String>):
    required: false
    

    The KMS key that encrypts and protects the data on your cluster. You can specify the ARN, ID, or alias of an existing key or have Amazon Web Services create a default key for you.

    
    
  • tags(impl Into<String>, impl Into<String>) / set_tags(Option<HashMap::<String, String>>):
    required: false
    

    A map of key and value pairs to use to tag your cluster.

    
    
  • client_token(impl Into<String>) / set_client_token(Option<String>):
    required: false
    

    A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Idempotency ensures that an API request completes only once. With an idempotent request, if the original request completes successfully, the subsequent retries with the same client token return the result from the original successful request and they have no additional effect.

    If you don’t specify a client token, the Amazon Web Services SDK automatically generates one.

    
    
  • multi_region_properties(MultiRegionProperties) / set_multi_region_properties(Option<MultiRegionProperties>):
    required: false
    

    The configuration settings when creating a multi-Region cluster, including the witness region and linked cluster properties.

impl Client

pub fn from_conf(conf: Config) -> Self

Creates a new client from the service Config.

Panics

This method will panic in the following cases:

• Retries or timeouts are enabled without a sleep_impl configured.
• Identity caching is enabled without a sleep_impl and time_source configured.
• No behavior_version is provided.

The panic message for each of these will have instructions on how to resolve them.

pub fn config(&self) -> &Config

Returns the client’s configuration.

impl Client

pub fn new(sdk_config: &SdkConfig) -> Self

Creates a new client from an SDK Config.

Panics

• This method will panic if the sdk_config is missing an async sleep implementation. If you experience this panic, set the sleep_impl on the Config passed into this function to fix it.
• This method will panic if the sdk_config is missing an HTTP connector. If you experience this panic, set the http_connector on the Config passed into this function to fix it.
• This method will panic if no BehaviorVersion is provided. If you experience this panic, set behavior_version on the Config or enable the behavior-version-latest Cargo feature.
