Enum Faulted 

pub enum Faulted {
    Missing,
    Warm,
    Served,
    Promoted,
}

What happened to a read of a key that may not have been in memory.

Variants

Missing

No such key. Nothing was read and nothing was written.

Warm

The value was in memory all along, so the output buffer was not touched and the caller should read the record the way it always does.

Served

Read from the file and deliberately left there, because one read is not enough to earn a slot in memory back.

Promoted

Read from the file and brought back into memory, so the next read of this key does not touch the device.
