Enum From 

pub enum From {
    Offset(u64),
    StateOnly,
}

Ask for state only, fetching no log bytes.

A plain wait wants rc, not output, and shipping the log to discard it would hold the lock for the transfer. Expressed as its own type rather than a sentinel offset: passing u64::MAX overflowed the +1 that tail -c +N needs and produced tail: Invalid argument, which surfaced as a spurious “lost contact while waiting” on every --wait --no-tail.

Variants

Offset(u64)

StateOnly
