Struct solana_ledger::blockstore_db::columns::ErasureMeta

source · 
pub struct ErasureMeta;
Expand description

The erasure meta column.

This column family stores ErasureMeta which includes metadata about dropped network packets (or erasures) that can be used to recover missing data shreds.

Its index type is crate::shred::ErasureSetId, which consists of a Slot ID and a FEC (Forward Error Correction) set index.
