Struct RecordMeta 

Source 
pub struct RecordMeta {
    pub partition: PartitionId,
    pub offset: i64,
    pub event_time_ms: i64,
    pub key_hash: Option<u64>,
}
Expand description

Per-record metadata. Copy, no drop glue — moves through operators for free and never touches the heap.

Fields§

§partition: PartitionId

Source partition this record was read from.

§offset: i64

Source offset (e.g. Kafka offset) of the originating payload.

§event_time_ms: i64

Event time in milliseconds since the epoch, as reported by the source (e.g. the Kafka message timestamp).

§key_hash: Option<u64>

Stable hash of the message key, when the source provides one; used by key-based shard routing.
