Struct solana_ledger::blockstore_db::columns::Root

source · 
pub struct Root;
Expand description

The root column.

This column family persists whether a slot is a root. Slots on the main fork will be inserted into this column when they are finalized.

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