Struct DynamodbConnector 

pub struct DynamodbConnector { /* private fields */ }

Provides a connection to DynamoDB, potentially managing test table lifecycles.

This struct encapsulates an AWS DynamoDB client (aws_sdk_dynamodb::Client). If configured with table definitions and a local endpoint in TableConfig, it will create uniquely named tables upon construction.

If the test_utils feature is enabled and delete_on_exit is true in the configuration, the created tables will be automatically deleted when this connector is dropped.

Implementations

impl DynamodbConnector

pub async fn load(config_path: impl AsRef<Path>) -> Result<Self>

Creates a new connector by loading configuration from a YAML file.

See TableConfig::load_from_file and DynamodbConnector::try_new.

Errors

Returns Err if loading the config file fails or if creating the connector fails (e.g., table creation fails, AWS configuration error).

pub fn client(&self) -> Result<&Client>

Returns a reference to the underlying aws_sdk_dynamodb::Client.

Errors

Returns Err (DynamoToolsError::Internal) if the client has already been taken (e.g., after Drop has started).

pub fn get_created_table_name(&self, base_name: &str) -> Option<&str>

Returns the unique name of a table created by this connector, given its base name.

The base_name corresponds to the table_name field within [TableInfo] in the configuration.

pub fn get_all_created_table_names(&self) -> &HashMap<String, String>

Returns a map of all tables created by this connector. Keys are the base names from the config, values are the unique created names.

pub async fn try_new(config: TableConfig) -> Result<Self>

Creates a new connector based on the provided TableConfig.

• Sets up AWS SDK configuration.
• Creates a aws_sdk_dynamodb::Client.
• Iterates through config.tables. For each TableInfo:
  • Attempts to create a DynamoDB table with a unique name derived from TableInfo.table_name.
  • Stores the mapping from the base name to the unique name.

Errors

Returns Err if AWS config fails, client creation fails, or any table creation fails.
