Implementors

impl<Cols, R, T> AfterJoin<R, T> for SelectCols<Cols>

Explicit columns + JOIN → R unchanged.

type NewRow = R

impl<M, Scope, R, T> AfterJoin<R, T> for Scoped<M, Scope>

where M: AfterJoin<R, T>,

type NewRow = <M as AfterJoin<R, T>>::NewRow

impl<R, T: HasSelectModel> AfterJoin<R, T> for SelectStar

SELECT * + JOIN → (CurrentRow, JoinedTable::SelectModel).

type NewRow = (R, <T as HasSelectModel>::SelectModel)

impl<R, T> AfterJoin<R, T> for SelectExpr

Raw/untyped + JOIN → R unchanged.

type NewRow = R

impl<Row, R, T> AfterJoin<R, T> for SelectAs<Row>

Explicit model + JOIN → R unchanged.

type NewRow = R
