Struct Client 

pub struct Client { /* private fields */ }

Client for Amazon SageMaker Feature Store Runtime

Client for invoking operations on Amazon SageMaker Feature Store Runtime. Each operation on Amazon SageMaker Feature Store Runtime 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_sagemakerfeaturestoreruntime::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_sagemakerfeaturestoreruntime::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 BatchGetRecord operation has a Client::batch_get_record, 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.batch_get_record()
    .expiration_time_response("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.

Implementations

impl Client

pub fn batch_get_record(&self) -> BatchGetRecordFluentBuilder

Constructs a fluent builder for the BatchGetRecord operation.

• The fluent builder is configurable:
  • identifiers(BatchGetRecordIdentifier) / set_identifiers(Option<Vec::<BatchGetRecordIdentifier>>):
    required: true
    

    A list containing the name or Amazon Resource Name (ARN) of the FeatureGroup, the list of names of Features to be retrieved, and the corresponding RecordIdentifier values as strings.

    
    
  • expiration_time_response(ExpirationTimeResponse) / set_expiration_time_response(Option<ExpirationTimeResponse>):
    required: false
    

    Parameter to request ExpiresAt in response. If Enabled, BatchGetRecord will return the value of ExpiresAt, if it is not null. If Disabled and null, BatchGetRecord will return null.

    
    
• On success, responds with BatchGetRecordOutput with field(s):
  • records(Option<Vec::<BatchGetRecordResultDetail>>):

    A list of Records you requested to be retrieved in batch.

  • errors(Option<Vec::<BatchGetRecordError>>):

    A list of errors that have occurred when retrieving a batch of Records.

  • unprocessed_identifiers(Option<Vec::<BatchGetRecordIdentifier>>):

    A unprocessed list of FeatureGroup names, with their corresponding RecordIdentifier value, and Feature name.

• On failure, responds with SdkError<BatchGetRecordError>

impl Client

pub fn delete_record(&self) -> DeleteRecordFluentBuilder

Constructs a fluent builder for the DeleteRecord operation.

    required: true
    

    The name or Amazon Resource Name (ARN) of the feature group to delete the record from.

    
    
  • record_identifier_value_as_string(impl Into<String>) / set_record_identifier_value_as_string(Option<String>):

  • event_time(impl Into<String>) / set_event_time(Option<String>):
    required: true
    

    Timestamp indicating when the deletion event occurred. EventTime can be used to query data at a certain point in time.

    
    
  • target_stores(TargetStore) / set_target_stores(Option<Vec::<TargetStore>>):
    required: false
    

    A list of stores from which you’re deleting the record. By default, Feature Store deletes the record from all of the stores that you’re using for the FeatureGroup.

    
    
  • deletion_mode(DeletionMode) / set_deletion_mode(Option<DeletionMode>):
    required: false
    

    The name of the deletion mode for deleting the record. By default, the deletion mode is set to SoftDelete.

    
    
• On success, responds with DeleteRecordOutput
• On failure, responds with SdkError<DeleteRecordError>

impl Client

pub fn get_record(&self) -> GetRecordFluentBuilder

Constructs a fluent builder for the GetRecord operation.

• The fluent builder is configurable:
  • feature_group_name(impl Into<String>) / set_feature_group_name(Option<String>):
    required: true
    

    The name or Amazon Resource Name (ARN) of the feature group from which you want to retrieve a record.

    
    
  • record_identifier_value_as_string(impl Into<String>) / set_record_identifier_value_as_string(Option<String>):

  • feature_names(impl Into<String>) / set_feature_names(Option<Vec::<String>>):
    required: false
    

    List of names of Features to be retrieved. If not specified, the latest value for all the Features are returned.

    
    
  • expiration_time_response(ExpirationTimeResponse) / set_expiration_time_response(Option<ExpirationTimeResponse>):
    required: false
    

    Parameter to request ExpiresAt in response. If Enabled, GetRecord will return the value of ExpiresAt, if it is not null. If Disabled and null, GetRecord will return null.

  • record(Option<Vec::<FeatureValue>>):

    The record you requested. A list of FeatureValues.

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.
