Andy Grove updated ARROW-2373:
------------------------------
Description:
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|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.
