Struct solana_ledger::blockstore_db::columns::Orphans

source ·

pub struct Orphans;

Expand description

The orphans column.

This column family tracks whether a slot has a parent. Slots without a parent are by definition orphan slots. Orphans will have an entry in this column family with true value. Once an orphan slot has a parent, its entry in this column will be deleted.

index type: u64 (see SlotColumn)
value type: bool
