// Lists the shards in a stream and provides information about each shard. This
// operation has a limit of 1000 transactions per second per data stream. When
// invoking this API, you must use either the StreamARN or the StreamName
// parameter, or both. It is recommended that you use the StreamARN input
// parameter when you invoke this API. This action does not list expired shards.
// For information about expired shards, see Data Routing, Data Persistence, and
// Shard State after a Reshard (https://docs.aws.amazon.com/streams/latest/dev/kinesis-using-sdk-java-after-resharding.html#kinesis-using-sdk-java-resharding-data-routing)
// . This API is a new operation that is used by the Amazon Kinesis Client Library
// (KCL). If you have a fine-grained IAM policy that only allows specific
// operations, you must update your policy to allow calls to this API. For more
// information, see Controlling Access to Amazon Kinesis Data Streams Resources
// Using IAM (https://docs.aws.amazon.com/streams/latest/dev/controlling-access.html)

// specify this parameter, the default behavior is for ListShards to list the
// shards starting with the first one in the stream. You cannot specify this
// parameter if you specify NextToken .
ExclusiveStartShardId *string
// The maximum number of shards to return in a single call to ListShards . The
// maximum number of shards to return in a single call. The default value is 1000.
// If you specify a value greater than 1000, at most 1000 results are returned.
// When the number of shards to be listed is greater than the value of MaxResults ,
// the response contains a NextToken value that you can use in a subsequent call
// to ListShards to list the next set of shards.
MaxResults *int32
// When the number of shards in the data stream is greater than the default value
// for the MaxResults parameter, or if you explicitly specify a value for
// MaxResults that is less than the number of shards in the data stream, the
// response includes a pagination token named NextToken . You can specify this
// NextToken value in a subsequent call to ListShards to list the next set of
// shards. Don't specify StreamName or StreamCreationTimestamp if you specify
// NextToken because the latter unambiguously identifies the stream. You can
// optionally specify a value for the MaxResults parameter when you specify
// NextToken . If you specify a MaxResults value that is less than the number of
// shards that the operation returns if you don't specify MaxResults , the response
// will contain a new NextToken value. You can use the new NextToken value in a
// subsequent call to the ListShards operation. Tokens expire after 300 seconds.
// When you obtain a value for NextToken in the response to a call to ListShards ,
// you have 300 seconds to use that value. If you specify an expired token in a
// call to ListShards , you get ExpiredNextTokenException .
NextToken *string
// Enables you to filter out the response of the ListShards API. You can only
// specify one filter at a time. If you use the ShardFilter parameter when
// invoking the ListShards API, the Type is the required property and must be
// specified. If you specify the AT_TRIM_HORIZON , FROM_TRIM_HORIZON , or AT_LATEST
// types, you do not need to specify either the ShardId or the Timestamp optional
// properties. If you specify the AFTER_SHARD_ID type, you must also provide the
// value for the optional ShardId property. The ShardId property is identical in
// fuctionality to the ExclusiveStartShardId parameter of the ListShards API. When
// ShardId property is specified, the response includes the shards starting with
// the shard whose ID immediately follows the ShardId that you provided. If you
// specify the AT_TIMESTAMP or FROM_TIMESTAMP_ID type, you must also provide the
// value for the optional Timestamp property. If you specify the AT_TIMESTAMP
// type, then all shards that were open at the provided timestamp are returned. If
// you specify the FROM_TIMESTAMP type, then all shards starting from the provided
// timestamp to TIP are returned.
ShardFilter *types.ShardFilter
// The ARN of the stream.
StreamARN *string
// Specify this input parameter to distinguish data streams that have the same
// name. For example, if you create a data stream and then delete it, and you later
// create another data stream with the same name, you can use this input parameter
// to specify which of the two streams you want to list the shards for. You cannot
// specify this parameter if you specify the NextToken parameter.
StreamCreationTimestamp *time.Time
// The name of the data stream whose shards you want to list. You cannot specify
// this parameter if you specify the NextToken parameter.
StreamName *string
