Transaction

Implementations

impl<'a, 'b, K: Key<'a>, V: Value> Transaction<'a, 'b, K, V>

pub fn get(&self, key: &K) -> Result<Option<V>, TransactionError<Error>>

Get the value associated with the specified key

pub fn set( &self, key: &K, value: &V ) -> Result<Option<V>, TransactionError<Error>>

Set the value associated with the specified key to the provided value

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

Remove the value associated with the specified key from the database

pub fn batch(&self, batch: &Batch<K, V>) -> Result<(), TransactionError<Error>>

Apply batch update

pub fn generate_id(&self) -> Result<u64, TransactionError<Error>>

Generate a monotonic ID. Not guaranteed to be contiguous or idempotent, can produce different values in the same transaction in case of conflicts
