Enum WalDisposition 

pub enum WalDisposition {
    Archive,
    Keep,
    Truncate,
}

What a snapshot does with the WAL it folds in.

Variants

Archive

Move it to wal.<N>.archive, where the history reads still find it. The default, and what every automatic snapshot does: a store should not forget how it got here in exchange for opening faster.

Keep

Leave wal.bin whole. Every pre-snapshot commit stays in the live WAL, and every open replays all of it.

Truncate

Drop it. The smallest directory and the fastest open, at the price of every commit before this point: node_history, edge_history, was_linked and open_at stop reaching them, and any archives an earlier snapshot left become unreachable too.
