Enum TableFunction 

pub enum TableFunction {
    Range,
    GenerateSeries,
}

Which table function a call resolved to.

An enum rather than a name, because the executor dispatches on this and a string comparison per operator build is a string comparison that can be spelled wrong.

Variants

Range

range(stop), range(start, stop), range(start, stop, step), stopping before the end.

GenerateSeries

The same three, stopping on the end.
