Enum KafkaMetadataColumn 

pub enum KafkaMetadataColumn {
    Key,
    Topic,
    Partition,
    Offset,
    Timestamp,
    TimestampType,
    Headers,
}

One selectable metadata column, in canonical output order.

Variants

Key

_key: the record key bytes, NULL for a record without a key.

Topic

_topic: the source topic.

Partition

_partition: the source partition.

Offset

_offset: the record offset.

Timestamp

_timestamp: the record timestamp in milliseconds, NULL when the broker reports none.

TimestampType

_timestamp_type: create_time, log_append_time or not_available.

Headers

_headers: every header in order, duplicates kept, values as nullable bytes.
