impl RocksDBWriteBatch[src]
pub fn len(&self) -> usize[src]
TODO(doc): @quake
pub fn size_in_bytes(&self) -> usize[src]
Return WriteBatch serialized size (in bytes).
pub fn is_empty(&self) -> bool[src]
TODO(doc): @quake
pub fn put(&mut self, col: Col, key: &[u8], value: &[u8]) -> Result<()>[src]

TODO(doc): @quake
pub fn delete_range(&mut self, col: Col, from: &[u8], to: &[u8]) -> Result<()>[src]
Remove database entries from start key to end key.
Removes the database entries in the range ["begin_key", "end_key"), i.e., including "begin_key" and excluding "end_key". It is not an error if no keys exist in the range ["begin_key", "end_key").
