Required Methods§
Provided Methods§
Sourcefn rewrite_with_input(
&self,
_input: PlanRef<C>,
_input_col_change: ColIndexMapping,
) -> (Self, ColIndexMapping)where
Self: Sized,
fn rewrite_with_input(

_input: PlanRef<C>,
_input_col_change: ColIndexMapping,
) -> (Self, ColIndexMapping)where
Self: Sized,
Rewrites the plan node according to the schema change of its input node during rewriting.
This function can be used to implement prune_col or
logical_rewrite_for_stream
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
