Struct mithril_signer::store::MKTreeStoreSqlite

pub struct MKTreeStoreSqlite { /* private fields */ }

A Merkle tree store with Sqlite backend

• This store is used to store the Merkle tree nodes in a Sqlite database with in memory mode.
• This store is not suited for proving, it is only used to store the compute the root of a Merkle tree.
• This store is slower than the in memory store but uses less memory which is important to minimize the signer footprint on the SPO infrastructure.
