Struct ColumnPair 

pub struct ColumnPair {
    pub local: ColumnName,
    pub related: ColumnName,
}

One extra equality on a relation hop: local is a column of the table before the hop (the parent row), related a column of the hop’s table. SQL equality, so a null on either side matches nothing.

Fields

local: ColumnName

The column on the table before the hop.

related: ColumnName

The column on the hop’s own table.
