[Slackbuilds-users] Questions with packaging a rust program.

[Charadon]

Hey all,
I'm wanting to make a Slackbuild for BLAKE3. The issue is that it's made 
in rust. Now rust has a thing that makes it pretty easy to vendor 
(`cargo vendor`) the dependencies, the issue is that, unless upstream 
provides their own vendored tarball, you'll be making your own.

So here are my questions:

1. Can I make a vendored tarball, upload it somewhere like archive.org 
and use that as a source? I know this is questionable security wise, but 
you should be able to replicate the archive using a `git clone` and 
`cargo vendor`
2. If not, can I include a script that downloads the source, runs cargo 
vendor, and makes a vendored tarball?
2. If not, how would you go about packaging a rust program? Is there any 
guide anywhere?
