    pub ops: Vec<DBOp>,
}

Write transaction. Batches a sequence of put/delete operations for efficiency.

Fields

ops: Vec<DBOp>

Database operations.

Methods

impl DBTransaction

pub fn new() -> DBTransaction

Create new transaction.

pub fn with_capacity(cap: usize) -> DBTransaction

Create new transaction with capacity.

pub fn put(&mut self, col: Option<u32>, key: &[u8], value: &[u8])

Insert a key-value pair in the transaction. Any existing value will be overwritten upon write.

pub fn put_vec(&mut self, col: Option<u32>, key: &[u8], value: Bytes)

Insert a key-value pair in the transaction. Any existing value will be overwritten upon write.

pub fn delete(&mut self, col: Option<u32>, key: &[u8])

Delete value by key.
