Detailed Description

template<typename ViewType>
struct cudf::custom_view_deleter< ViewType >

functor for a custom deleter to a unique_ptr of table_view

When converting from an ArrowDeviceArray, there are cases where data can't be zero-copy (i.e. bools or non-UINT32 dictionary indices). This custom deleter is used to maintain ownership over the data allocated since a cudf::table_view doesn't hold ownership.
