| Fact | rustup | RVM |
|---|---|---|
| Purpose | rustup installs the Rust programming language from official release channels. | RVM is a command-line tool for installing and managing multiple Ruby environments, from interpreters to gem sets. |
| Security | rustup downloads over HTTPS but does not yet validate download signatures. | RVM says it cryptographically signs releases and the installer script, and verifies signatures during updates. |
| Support | The rustup site directs users to the Rust community for help, and the rustup book points to the GitHub issue tracker for problems. | RVM is maintained by community volunteers, with support through issue trackers and pull requests. |
