Struct WriteBatch 

Source 
pub struct WriteBatch<'db, K: StoreKey + Send, S: ParallelScheduler, const FAMILIES: usize> { /* private fields */ }
Expand description

A write batch.

Implementations§

Source§

impl<'db, K: StoreKey + Send + Sync, S: ParallelScheduler, const FAMILIES: usize> WriteBatch<'db, K, S, FAMILIES>

Source

pub fn put(&self, family: u32, key: K, value: ValueBuffer<'_>) -> Result<()>

Puts a key-value pair into the write batch.

Source

pub fn delete(&self, family: u32, key: K) -> Result<()>

Puts a delete operation into the write batch.

Source

pub unsafe fn flush(&self, family: u32) -> Result<()>

Flushes a family of the write batch, reducing the amount of buffered memory used. Does not commit any data persistently.

§Safety

Caller must ensure that no concurrent put or delete operation is happening on the flushed family.
