impl RocksDBWriteBatch
sourcepub fn size_in_bytes(&self) -> usize
pub fn size_in_bytes(&self) -> usize
Return WriteBatch serialized size (in bytes).
sourcepub fn put(&mut self, col: Col, key: &[u8], value: &[u8]) -> Result<()>
pub fn put(&mut self, col: Col, key: &[u8], value: &[u8]) -> Result<()>
Write the bytes into the given column with associated key.
sourcepub fn delete(&mut self, col: Col, key: &[u8]) -> Result<()>
pub fn delete(&mut self, col: Col, key: &[u8]) -> Result<()>
Delete the data associated with the given key and given column.
sourcepub fn delete_range<K: AsRef<[u8]>>(
&mut self,
col: Col,
range: impl Iterator<Item = K>
) -> Result<()>
pub fn delete_range<K: AsRef<[u8]>>(
&mut self,
col: Col,
range: impl Iterator<Item = K>
) -> Result<()>
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”).
