[rust-dev] Rust BigInt

[Lee Wei Yen]

Hi all!

I?ve just started learning to use Rust now, and so far it?s been everything I wanted in a language.

I saw from the docs that the num::bigint::BigInt type has been deprecated - does it have a replacement?

It was moved to https://github.com/rust-lang/num

There's also https://github.com/thestinger/rust-gmp which binds to GMP.

GMP has better time complexity for the operations, significantly faster
constant factors (10-20x for some operations) and more functionality.

It also doesn't have lots of showstopper bugs since it's a mature library.

Disclaimer, for the unwary, GMP is a GPL library; so using it implies
complying with the GPL license.

LGPL afaik, so you can dynamically link with it in any case.

Static linking of a proprietary application is fine too, as long as
linkable object files are provided so the user can replace GMP with a
patched / updated library.

Not true. It's under the LGPL license and proprietary applications can
both dynamically link and statically link against it. The end user needs
to be able to replace the library - which is a given with dynamic
linking, and can be done with static linking by providing linkable
object files rather than a binary (or both). Rust itself relies on
plenty of GPL with linking exception / LGPL code like glibc / libgcc /
libunwind.
