Required Methods

fn affected_rows(&self) -> i32

fn precision(&self) -> Precision

fn fields(&self) -> &[Field]

fn summary(&self) -> (usize, usize)

Provided Methods

fn num_of_fields(&self) -> usize

fn blocks(&mut self) -> IBlockIter<'_, Self>

Iterator for raw data blocks.

fn rows(&mut self) -> IRowsIter<'_, Self>

Iterator for querying by rows.

fn deserialize<T: DeserializeOwned>( &mut self, ) -> Map<IRowsIter<'_, Self>, fn(RawResult<RowView<'_>>) -> RawResult<T>>

fn to_rows_vec(&mut self) -> RawResult<Vec<Vec<Value>>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
