pub type ExprPropertiesNode = ExprContext<ExprProperties>;

Represents a PhysicalExpr node with associated properties (order and range) in a context where properties are tracked.

Aliased Type

struct ExprPropertiesNode {
    pub expr: Arc<dyn PhysicalExpr>,
    pub data: ExprProperties,
    pub children: Vec<ExprContext<ExprProperties>>,
}

Fields

expr: Arc<dyn PhysicalExpr>

The physical expression associated with this context.

data: ExprProperties

Custom data payload of the node.

children: Vec<ExprContext<ExprProperties>>

Child contexts of this node.

Implementations

impl ExprPropertiesNode

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

Constructs a new ExprPropertiesNode with unknown properties for a given physical expression. This node initializes with default properties and recursively applies this to all child expressions.
