}

A borrowed view on the valid rows in a column of a crate::buffers::ColumnarRowSet.

For columns of fixed size types, which are guaranteed to not contain null, a direct access to the slice is offered. Buffers over nullable columns can be accessed via an iterator over options.

Variants

Text(TextColumnIt<'a>)

Since we currently always have an indicator buffer for the text length anyway, there is no NULL values are always represntable and there is no dedicated representation for none NULL values.
