pub fn put<T, K>( &self, writer: &mut Writer<T>, k: K, v: &Value<'_> ) -> Result<(), StoreError>where T: BackendRwTransaction<Database = D>, K: AsRef<[u8]>,
Insert a value at the specified key.
This put will allow duplicate entries. If you wish to have duplicate entries
rejected, use the put_with_flags
function and specify NO_DUP_DATA
