Struct aws_sdk_dynamodb::paginator::ScanPaginator

pub struct ScanPaginator { /* private fields */ }

Paginator for Scan

Implementations

impl ScanPaginator

pub fn page_size(self, limit: i32) -> Self

Set the page size

Note: this method will override any previously set value for limit

pub fn items(self) -> ScanPaginatorItems

Create a flattened paginator

This paginator automatically flattens results using items. Queries to the underlying service are dispatched lazily.

pub fn stop_on_duplicate_token(self, stop_on_duplicate_token: bool) -> Self

Stop paginating when the service returns the same pagination token twice in a row.

Defaults to true.

For certain operations, it may be useful to continue on duplicate token. For example, if an operation is for tailing a log file in real-time, then continuing may be desired. This option can be set to false to accommodate these use cases.

pub fn send(
    self
) -> impl Stream<Item = Result<ScanOutput, SdkError<ScanError>>> + Unpin

Create the pagination stream

Note: No requests will be dispatched until the stream is used (eg. with .next().await).
