[−][src]Struct sled::Batch
A batch of updates that will be applied atomically to the Tree.
Examples
use sled::{Batch, open}; let db = open("batch_db_2")?; db.insert("key_0", "val_0")?; let mut batch = Batch::default(); batch.insert("key_a", "val_a"); batch.insert("key_b", "val_b"); batch.insert("key_c", "val_c"); batch.remove("key_0"); db.apply_batch(batch)?; // key_0 no longer exists, and key_a, key_b, and key_c // now do exist.
