Enum ReadOnlyReason 

pub enum ReadOnlyReason {
    Locked(Holding),
    Reading,
    HistoryBroken(BreakReport),
    WriteFailed(Error),
}

Why a container is open without the right to write it. Every arm is something the user must be told, which is why this is not a bool.

Variants

Locked(Holding)

Another live process holds the advisory lock.

Reading

Opened to be read rather than edited — someone else’s document being looked at. The lock was never claimed, which is the whole point: a reader must not stand between an owner and their own document.

HistoryBroken(BreakReport)

The manifest does not verify; only the prefix before the break is real.

WriteFailed(Error)

A row could not be appended, so this session’s document and the files have parted ways. Nothing more is written until the container is reopened.
