Struct NativeBatch 

Source 
pub struct NativeBatch {
    pub format: NativeFormat,
    pub payload: NativePayload,
    pub csv: CsvDialect,
    pub records: Option<u64>,
    pub bookmark: Option<Value>,
}
Expand description

One native-format byte batch handed from a source’s stream_native to a sink’s load_native.

bookmark carries the same checkpoint semantics as StreamPage: whenever it is Some, the pipeline flushes the sink and persists the bookmark before polling the next batch.

Fields§

§format: NativeFormat

The wire format of payload.

§payload: NativePayload

The batch bytes.

§csv: CsvDialect

CSV dialect (only meaningful when format == Csv).

§records: Option<u64>

Row count if the source knows it (used for metrics; None if unknown).

§bookmark: Option<Value>

Checkpoint bookmark, or None for a mid-stream batch.

Implementations§

Source§

impl NativeBatch
