From the Rust Forge Documentation: https://forge.rust-lang.org/infra/other-installation-methods.html#standalone-installers Architectures amd64 and arm64 have musl tarballs available, so why shouldn't gentoo musl lift the mask? Reproducible: Always
Have you tested it? e.g. is rust-bin package already able to fetch those tarballs and works if you unmask yourself
I wanted to install it for aarch64 but looks like the rust-toolchain.eclass didn't include the aarch64-unknown-linux-musl target because it was recently added in 1.48.0. Will test this soon on an amd64 machine.
It does work for both 1.47 and 1.46 and rustc is working fine. I am able to build binaries and execute them without any errors. One thing: rust-bin isn't really masked on musl amd64. I am able to emerge without any unmasking on a clean chroot. I don't know if that was intended.

Ah yes, it's unmasked specifically for amd64 given it's available already. So this is only about aarch64.
I think the mask on firefox should also be removed because rust works on musl now
I can confirm at least a simple hello world rust program works with aarch64 musl rust after adding support to the eclass.
1.50.0 should have it, landing soon to the repo. if works fine I can backport back to 1.48.0 if needed

ok support added for both bin and source versions, as for esclass. not tested much as I lack musl arm64 installations currently. please report how it works, it's masked for now still. if I receive positive reports I'll proceed with unmasking, hopefully will do my tests as well.
I tried to emerge rust-bin-1.50.0 on aarch64-gentoo-linux-musl, this is what I get: >>> Unpacking rust-1.50.0-aarch64-unknown-linux-gnu.tar.xz to /var/tmp/portage/dev-lang/rust-bin-1.50.0/work mv: cannot stat '/var/tmp/portage/dev-lang/rust-bin-1.50.0/work/rust-1.50.0-aarch64-unknown-linux-musl': No such file or directory (The directory '/var/tmp/portage/dev-lang/rust-bin-1.50.0/work/rust-1.50.0-aarch64-unknown-linux-gnu' exists, but that's -gnu not -musl)

thank you very much for bringing this into the tree, I'm now trying to get an armv7a-unknown-linux-musleabihf std lib via the RUST_CROSS_TARGETS=() env file hack, lets hope for the best :-)
it's still masked in musl profile https://gitweb.gentoo.org/repo/gentoo.git/tree/profiles/features/musl/package.mask#n280
