Method with_expr_adapter

datafusion/datasource/src/file_scan_config/mod.rs:485–491

Register an expression adapter used to adapt filters and projections that are pushed down into the scan from the logical schema to the physical schema of the file. This can include things like: - Column ordering changes - Handling of missing columns - Rewriting expression to use pre-computed values or file format specific optimizations

        mut self,
        expr_adapter: Option<Arc<dyn PhysicalExprAdapterFactory>>,
    )
