    // Required methods
    fn context(&self) -> &dyn OperandContext<Self>;

Required Methods

fn context(&self) -> &dyn OperandContext<Self>

fn as_plan_node(&self) -> &dyn PlanNode

fn from_context(context: Arc<dyn OperandContext<Self>>) -> Self

Provided Methods

fn new<C: OperandContext<Self>>(context: C) -> Self

fn explain(&self) -> Explanation<'_>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
