Trait Implementations

impl<'a> AsyncIterator for RowIterator<'a>

fn next<'life0, 'async_trait>(
    &'life0 mut self
) -> Pin<Box<dyn Future<Output = Result<Option<Row>, Status>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

next returns the next result. Its second return value is None if there are no more results.
