RecordRef

Enum RecordRef 

Source
pub enum RecordRef<'a> {
    Lean {
        batch: &'a LeanBatch,
        record: &'a LeanRecord,
    },
    Full(&'a Record),
}
Expand description

One record, without a record having been built for it.

A key, value or header list is materialised when asked for, not at decode time — which is the point: every slice of a batch buffer increments the same atomic refcount, so a caller that skips a record should not pay for it.

Variants§

Lean

Fields

§batch: &'a LeanBatch
§record: &'a LeanRecord
§

Full(&'a Record)

From a batch the lean reader handed back.
