>                 URL: https://issues.apache.org/jira/browse/ARROW-2373
>             Project: Apache Arrow
>          Issue Type: New Feature
>          Components: Rust
>            Reporter: Andy Grove
>            Priority: Minor
>
> The current Rust implementation of Buffer<T> relies on libc and unsafe code to allocate byte-aligned buffers.
> It would be nice to find a safer way to do this.
> Rust 1.25 added support for byte-aligned structs, but that doesn't help.
> I have started a discussion in the Rust develop forum about adding support for byte-aligned Vec ([https://internals.rust-lang.org/t/byte-aligned-vec/7200).]
> RawVec has been suggested too, but that required rust nightly, which doesn't seem great to me.
