Struct TransactionalTree

pub struct TransactionalTree<'a, V, E, F>(/* private fields */);

A transaction that will be applied atomically to the Tree.

Implementations

where E: Encoding<HashSet<IVec>> + Encoding<DateTime<Utc>> + 'static, F: Encoding<V> + 'static,

pub fn insert<K>( &self, key: K, value: V, ) -> ConflictableTransactionResult<Result<Option<V>>>

where IVec: From<K>, K: AsRef<[u8]>,

Set a key to a new value

pub fn remove<K>( &self, key: K, ) -> ConflictableTransactionResult<Result<Option<V>>>

where IVec: From<K>, K: AsRef<[u8]>,
