Method into_array

datafusion/expr-common/src/columnar_value.rs:136–141

Convert any [`Self::Scalar`] into an Arrow [`ArrayRef`] with the specified number of rows by repeating the same scalar multiple times, which is not as efficient as handling the scalar directly. [`Self::Array`] will just be returned as is. See [`Self::into_array_of_size`] if you need to validate the length of the output array. See [`Self::values_to_arrays`] to convert multiple columnar values in
