Struct Inner 

struct Inner {
    generation: u64,
    expr: Arc<dyn PhysicalExpr>,
}

Fields

generation: u64

A counter that gets incremented every time the expression is updated so that we can track changes cheaply. This is used for PhysicalExpr::snapshot_generation to have a cheap check for changes.

expr: Arc<dyn PhysicalExpr>

Implementations

impl Inner

fn new(expr: Arc<dyn PhysicalExpr>) -> Self

fn expr(&self) -> &Arc<dyn PhysicalExpr>

Clone the inner expression.
