> The Rust IPC writer types have a destructor that automatically writes the
> footer if necessary. This is not ideal, though, since it can hide errors. For
> example, if a web server is streaming data to a client in the Arrow IPC
> format and it encounters an internal error trying to generate the next batch,
> the outbound stream will appear valid to the client as the footer will
> automatically be written out but some amount of data will actually be
> missing. If the footer was not automatically written, the client would
> properly detect the truncation.
> For reference, the C++ implementation does not attempt to write the footer
> implicitly on drop.
