Struct TxId 

pub struct TxId {
    pub pack_id: Option<u64>,
    pub extent: Option<(u64, u64)>,
    pub push_seq: Option<u64>,
}

The receipt for one durable transaction.

Not an opaque counter: a push spans two durable logs — the one that claims the pack’s extent and the one whose frame is the ref transaction — and a caller that has to prove a push landed needs a coordinate in each. Every field is applied output, read back from what was written.

Fields

pack_id: Option<u64>

Dense id the push path assigned this pack, and the key the indexed bit is kept under. None when the transaction carried no pack.

extent: Option<(u64, u64)>

Where the verbatim pack bytes are, as the journal row records them.

push_seq: Option<u64>

The ref log’s ordering authority for the ref namespace. None when the transaction carried no ref update.
