Method build

src/clusterd-test-driver/src/dataflow.rs:281–286

Insert a MIR object to compute, bound to `id`. `expr` is wrapped via [`OptimizedMirRelationExpr::declare_optimized`]; the caller is responsible for any optimization (see the type-level contract). The object's relation type is recorded so a later [`Self::export_index`] over `id` can derive its `on_type`.

(&mut self, id: GlobalId, expr: MirRelationExpr)

    /// object's relation type is recorded so a later [`Self::export_index`] over `id`
    /// can derive its `on_type`.
    pub fn build(&mut self, id: GlobalId, expr: MirRelationExpr) -> &mut Self {
        self.types.insert(id, expr.typ());
        self.mir
            .insert_plan(id, OptimizedMirRelationExpr::declare_optimized(expr));
        self
    }

    /// Export an index `index_id` arranging `on_id` by `key_cols`.
