pub type LeftJoinQuerySource<Left, Right, On = <Left as JoinTo<Right>>::OnClause> = JoinOn<Join<Left, Right, LeftOuter>, On>;

A query source representing the left outer join between two tables. For example, for the left join between three tables that implement JoinTo: LeftJoinQuerySource<LeftJoinQuerySource<table1, table2>, table3> Which conveniently lets you omit the exact join condition.
