Method declare_optimized

src/expr/src/lib.rs:65–67

Declare that the input `expr` is optimized, without actually running it through an optimizer. This can be useful to mark as optimized literal `MirRelationExpr`s that are obviously optimal, without invoking the whole machinery of the optimizer.

(expr: MirRelationExpr)

    /// `MirRelationExpr`s that are obviously optimal, without invoking the whole
    /// machinery of the optimizer.
    pub fn declare_optimized(expr: MirRelationExpr) -> OptimizedMirRelationExpr {
        OptimizedMirRelationExpr(expr)
    }

    /// Get mutable access to the inner [MirRelationExpr]
    ///
