Struct LeaseLedger

Source

pub struct LeaseLedger { /* private fields */ }

Expand description

Worker lease ledger (spec section 12.10: “worker lease expiry cleans abandoned fragments”). Workers are keyed by the tablet whose data they serve this wave; the node-level binding lands with the transport wave.
