It's an unofficial port of the New Relic Go agent to Rust.
Unlike the one based on the C sdk, it is completely thread-safe and works alone.
A very basic transaction works. Error handling is mostly lacking.
The library reports itself as Go because the New Relic server (of course) doesn't have a support for Rust.
I consider it a port of the New Relic Go agent, therefore (perhaps) inheriting copyrights from the original source code.
