Struct LostValue 

Source 
pub struct LostValue<V> {
    pub incarnation: u64,
    pub value: ColumnValue<V>,
    pub replaced_by: WriteId,
}
Expand description

A value replaced only by writes that had not read it (_coven_lost).

Fields§

§incarnation: u64

The incarnation in which the value was set.

§value: ColumnValue<V>

The value, with its original reference metadata.

§replaced_by: WriteId

The earliest delete, or otherwise the current winning setter.
