API

new: directory -> Store

let mut accounts_store: Store<Hash, Account> = Store::new("./ndb")?;

put: &key, &value

accounts_store.put(&Hash, &Account)?;

get: &key -> value

let account = accounts_store.get(&Hash)?;

delete: &key

accounts_store.delete(&Hash)?;

Future

• 🚀 batching requests for performance
• 📥 store.put_many(&[(K,V)])
• 📤 store.get_many(&[K]) -> Vec<(K,V)>
• 🦾 store.iter(lambda) -> Vec<_>
• 🧠 store.fold(accumulator, lambda) -> accumulator
• 🔍 store.any(lambda) -> V
• 🐘 store.memory(size)
• 📸 snapshots
