rustup: installing it via portage?

[OwenChia]

Rustup is the recommended method of installation now, should we write a ebuild for it like archlinux?

Is there a reason not to install it via portage?

UPDATE: the reason actually exists: rust-lang/rustup#953

[OwenChia]

better support for cross-compilation?

It is also unclear how to optionally get the unstable compiler (needed for some features) that is very straightforward with rustup.

[o01eg]

unstable compiler is dev-lang/rust-9999 or dev-lang/rust-bin-9999

It looks like there is a way to work around this that should be simple to integrate into a portage-installed rustup: rust-lang/rustup#953 (comment)

You can bypass the check by setting RUSTUP_INIT_SKIP_PATH_CHECK to yes:

I'm about to switch over to gentoo from debian and would be happy to take this issue on as my first contribution to the community.
