Struct OwnedWriteBatch 

pub struct OwnedWriteBatch { /* private fields */ }

An atomic write batch

Allows atomically writing across keyspaces inside the Database.

Implementations

impl WriteBatch

pub fn with_capacity(db: Database, capacity: usize) -> Self

Initializes a new write batch with preallocated capacity.

Note

“Capacity” refers to the number of batch item slots, not their size in memory.

pub fn len(&self) -> usize

Gets the number of batched items.

pub fn is_empty(&self) -> bool

Returns true if there are no batches items (yet).

pub fn durability(self, mode: Option<PersistMode>) -> Self

Sets the durability level.

pub fn insert<K: Into<UserKey>, V: Into<UserValue>>( &mut self, p: &Keyspace, key: K, value: V, )

Inserts a key-value pair into the batch.

pub fn remove<K: Into<UserKey>>(&mut self, p: &Keyspace, key: K)

Removes a key-value pair.

pub fn commit(self) -> Result<()>

Commits the batch to the Database atomically.

Errors

Will return Err if an IO error occurs.
