Project:Rust

The goal of this project is to provide proper packaging of Rust and Cargo for use within the Gentoo ecosystem. The project also maintains an eclass called cargo which can be utilized https://github.com/cardoe/cargo-ebuild to generate ebuilds for Cargo based projects to be built by a Gentoo package manager.

Network-less builds
It is important to ensure that users of network-less builds or network sandboxing are able to build Rust and Cargo so you should test your ebuilds with the following:

Ensure the binary is up to date
When bumping please ensure that  is kept at the same release. This avoids issues with people mixing versions that Portage can't reason around (note: add the bug #).

Cargo based projects
This includes Cargo itself (and soon Rust itself). You should always use https://github.com/cardoe/cargo-ebuild to gather the proper dependencies that need to appear in your ebuild. More than likely this utility will generate a proper ebuild for you. If the package in question contains a Cargo.lock file you MUST not change the dependencies that cargo ebuild generates because you will break offline installs.
