Struct Record 

Source 
pub struct Record<T> {
    pub payload: T,
    pub meta: RecordMeta,
    pub ack: AckRef,
}
Expand description

A record flowing through the chain.

Fields§

§payload: T

The payload; may borrow from the source’s buffers.

§meta: RecordMeta

Copyable metadata, preserved automatically by operators.

§ack: AckRef

Acknowledgement handle shared by every record derived from the same source poll batch. Dropping it (filter, error-skip, or successful write) resolves this record’s share of the batch.

Implementations§

impl<T> Record<T>

Source

pub fn map<U>(self, f: impl FnOnce(T) -> U) -> Record<U>
