SubscribeToShardEvent

Struct SubscribeToShardEvent 

Source
#[non_exhaustive]
pub struct SubscribeToShardEvent { pub records: Vec<Record>, pub continuation_sequence_number: String, pub millis_behind_latest: i64, pub child_shards: Option<Vec<ChildShard>>, }
Expand description

After you call SubscribeToShard, Kinesis Data Streams sends events of this type over an HTTP/2 connection to your consumer.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§records: Vec<Record>

§continuation_sequence_number: String

Use this as SequenceNumber in the next call to SubscribeToShard, with StartingPosition set to AT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER. Use ContinuationSequenceNumber for checkpointing because it captures your shard progress even when no data is written to the shard.

§millis_behind_latest: i64

The number of milliseconds the read records are from the tip of the stream, indicating how far behind current time the consumer is. A value of zero indicates that record processing is caught up, and there are no new records to process at this moment.

§child_shards: Option<Vec<ChildShard>>

The list of the child shards of the current shard, returned only at the end of the current shard.

Implementations§

impl SubscribeToShardEvent

Source

pub fn records(&self) -> &[Record]

Source

pub fn continuation_sequence_number(&self) -> &str

Use this as SequenceNumber in the next call to SubscribeToShard, with StartingPosition set to AT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER. Use ContinuationSequenceNumber for checkpointing because it captures your shard progress even when no data is written to the shard.

Source

pub fn millis_behind_latest(&self) -> i64

The number of milliseconds the read records are from the tip of the stream, indicating how far behind current time the consumer is. A value of zero indicates that record processing is caught up, and there are no new records to process at this moment.

Source

pub fn child_shards(&self) -> &[ChildShard]

The list of the child shards of the current shard, returned only at the end of the current shard.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .child_shards.is_none().
