When not to use rusty
- You need macOS or Windows hosts — rusty will never support them.
- You require a mature, production-proven cargo-only stack today.
- Your policy forbids source-available (non-OSI) licenses without a commercial deal.
- You need third-party binary redistribution or public rehosting without a commercial license.
