pub struct ScalarFunctionArgs {
pub args: Vec<ColumnarValue>,
pub arg_fields: Vec<Arc<Field>>,
pub number_rows: usize,
pub return_field: Arc<Field>,
}Expand description
Arguments passed to ScalarUDFImpl::invoke_with_args when invoking a
scalar function.
Fields§
§args: Vec<ColumnarValue>The evaluated arguments to the function
arg_fields: Vec<Arc<Field>>Field associated with each arg, if it exists
number_rows: usizeThe number of rows in record batch being evaluated
return_field: Arc<Field>The return field of the scalar function returned (from return_type
or return_field_from_args) when creating the physical expression
from the logical expression
