Remainder,
}Expand description
Column selector type
Variants§
Indices(Vec<usize>)
Select columns by indices
Names(Vec<String>)
Select columns by name (when working with named columns)
DataType(DataType)
Select columns by data type (would require runtime type checking)
Remainder
Select all remaining columns
