SCUSS] Changing type of array lengths
On windows it depends if it's a 32 or 64 bit binary, like on every other system
as well.
usize is usually used by Rust containers for indexing (see for example Vec in
the standard library) and I found it personally very annoying if libraries

What would be the argument for using usize over i64/u64? Is usize 64
bits in Rust when compiling on Windows?

One question here is: do we want to support datasets with more than 4G entries
on 32bit systems? If so, how would this even be possible (since you cannot just
fit that much data in any addressable memory chunk in Rust)?
So I would say: usize is idiomic and supports large enough datasets on the
Thanks for raising the issue, Paddy. In C++/Python/R we often work
with vary large contiguous datasets, so having support for 64-bit
lengths is important. If supporting this in Rust is not a hardship, I
think it's a good idea.
For IPC (shared memory) or RPC (Flight / gRPC), in many cases it would
All,
As part of the PR for ARROW-3347 there was a discussion regarding the type that
should be used for anything that measures the length of an array, i.e. len and
capacity.
The result of this discussion was that the Rust implementation should switch to
using usize as the type for representin
