A program being written in rust itself doesn’t guarantee anything, but it tells you what you’ll probably find:

• Utf-8 support
• No shenanigans with installations, dynamic libraries and such. Just download and execute.
• Multi-platform support
• Low resource usage.
• semver.
• Compile with just 1 command if you want to.
• MIT/apache2 license.
• No memory leaks.
• If it crashes, at least it will probably log out something more helpful than “SEGFAULT”.

Many of those are highly positive to the end consumer.
