Expand description

A builder for GetShardIteratorOutput.

Implementations§

source §

impl Builder

source

pub fn shard_iterator(self, input: impl Into<String>) -> Self

The position in the shard from which to start reading stream records sequentially. A shard iterator specifies this position using the sequence number of a stream record in a shard.

source

pub fn set_shard_iterator(self, input: Option<String>) -> Self

The position in the shard from which to start reading stream records sequentially. A shard iterator specifies this position using the sequence number of a stream record in a shard.
