On behalf of the Rust Team=E2=84=A2=C2=B9 we'd like to check our rust sourc= e tarballs for any hidden binaries=C2=B2 and to do a mass upgrade of many of the crate= s. Currently there are many crates queued up in the staging branch but we'd like to pull them out and run a rust-team branch. As a project we haven't setup anything for starting the team-based branches and upgrades, and the Rust Team volunteers to go first. Although the rust team would consider adding librsvg (and python-cryptography) to our list of packages, we'd like to not touch it this round, to keep it "small" (as far as rust goes) as a test. =C2=B9 Help wanted =C2=B2 https://issues.guix.gnu.org/61352 --=20 Efraim Flashner =D7=90=D7=A4=D7=A8=D7=99=D7=9D = =D7=A4=D7=9C=D7=A9=D7=A0=D7=A8 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --C4cGzdr1p6InZX6w Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAmPrXukACgkQQarn3Mo9 g1HDdBAApZp5Yuf+617/tM3Ik4fvo6uavkW+j87lurmyjNKUHc2Eh2th5GNpa/Bc 9fQH5dCLQw0iy1KtBVeuzrIt8DhgVxk4bC9WZMb3qGQ4ud7CqNb62XnUXcMKTsMn qgwhpkzD4Zvfu/4pi74dXjavkJmKOIpK+jlJ8iKCitJq9KYqoBw4OZT5EG1HqdTE KBTyLbduA1skFcTihfwem8ljsW0F2o2E+9zhNDCPRx18Ca3i13hvnLETuqH4OzBN DwDPVbte3JjQaQCzuPKL3m4xjgrmK/0Euc2I3il6ZUuCTKmajLJ/RmHYU+3Hedt2 a/ecr8SBS02WWjL5XcvEBVtSJfFKYTYFyK9yPDVvYT+ZyERhq+KMsPCm32oC25zG yPHa4vH08LN6DK4Yg1KCUHaIheGfAvK+J6R+QBxw/vFSZ7uycCgtBTJFyvuAwuKi S1AgZfR0+9xpNw7msEsrL8W9XvnV+Y9GZ1SwQK7IFWjaDOFAz69p2x5BfHZKp9K2 XsRKb5M1pQt1PebOOnVdS/BGVFEDcLCJbLe5ymRtQQfmFlq8r7EOV498YwuxhuJZ t4V7cLJSQBxytMwjClqTFzaHJVRUPJaQ/YiWyetqNuXpXjL8QDJEe41dH/U6qmeH 0C+wJj/wUC0oohZ0hRcUJ+30iQ3hTZA3hWcKLMRIuzZm14QzhYk= =kEZF -----END PGP SIGNATURE----- --C4cGzdr1p6InZX6w--
