I have some libraries that I tend to rewrite for every new language I learn, but once I wrote something in Rust, its written once and for all, highly efficient and considerably safe, and I can use it from all other languages (node, elixir, ruby, ...).
And I have high hopes for webassembly to replace the brittle and overcomplicated frontend stuff in the next years, Rust should be the ideal candidate to write enterprisey stuff which must not fail.
