A trait for table function implementations

Provided Methods

fn call( &self, _exprs: &[Expr], ) -> Result<Arc<dyn TableProvider>, DataFusionError>

👎Deprecated since 53.0.0:

Implement TableFunctionImpl::call_with_args instead

Create a table provider

fn call_with_args( &self, args: TableFunctionArgs<'_, '_>, ) -> Result<Arc<dyn TableProvider>, DataFusionError>

Create a table provider

Dyn Compatibility

This trait is dyn compatible.

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