Enum Barrier 

pub enum Barrier {
    None,
    Data,
    Full,
}

Which durability barrier a caller wants. Named rather than boolean, because true does not say what was promised.

There is deliberately no generic sync() on FileIo. One existed briefly and called File::sync_data, which issues F_FULLFSYNC on macOS and fdatasync on Linux – the same call meaning two different promises depending on the platform, which is exactly the ambiguity sync_data/sync_full exist to remove. Leaving a sync() beside them preserves the bug in the one place nobody looks: the buffer pool’s own checkpoint flush went through it, ungoverned by any SyncMode, even after Store::commit stopped being ambiguous.
