Struct DynamoDb 

pub struct DynamoDb { /* private fields */ }

A DynamoDB Driver backed by the AWS SDK.

Create one with DynamoDb::from_env to load AWS credentials and region from the environment, or DynamoDb::new / DynamoDb::with_sdk_config for manual setup.

Implementations

impl DynamoDb

pub fn new(url: String, client: Client) -> Self

Create driver with pre-built client (backward compatible, synchronous)

pub async fn from_env(url: String) -> Result<Self>

Create driver loading AWS config from environment (async factory) Reads: AWS_REGION, AWS_ENDPOINT_URL_DYNAMODB, AWS credentials, etc.

pub fn with_sdk_config(url: String, sdk_config: &SdkConfig) -> Self

Create driver with custom SdkConfig (synchronous)

Trait Implementations

impl Clone for DynamoDb

fn clone(&self) -> DynamoDb

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DynamoDb

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Driver for DynamoDb

fn url(&self) -> Cow<'_, str>

Returns the URL this driver is connecting to.

fn capability(&self) -> &'static Capability

Describes the driver’s capability, which informs the query planner.

fn connect<'life0, 'life1, 'async_trait>( &'life0 self, cx: &'life1 ConnectContext, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Connection>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Creates a new connection to the database.

fn generate_migration(&self, _schema_diff: &Schema<'_>) -> Migration

Generates a migration from a diff::Schema.

fn reset_db<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Drops the entire database and recreates an empty one without applying migrations.

fn max_connections(&self) -> Option<usize>

Returns the maximum number of simultaneous database connections supported. For example, this is Some(1) for the in-memory SQLite driver which cannot be pooled.
