Hey, I'm an engineer at Gremlin! When you install Gremlin onto your linux hosts for infrastructure experiments, you're using binaries that were completely written in Rust. I would be lying if I said there wasn't a bit of a learning curve (coming from mostly working with Java). Most of that can be attributed to the memory management concepts built into Rust. At first you fight the compiler a bit (asking things like, why am I not allowed to reference this variable?!), but you soon learn to love and rely on the compiler as it builds more confidence in the runtime behavior of the product.

One game changer for Rust is the treatment of Errors as first class citizens. It's literally built into the native types that Rust wants you to work with. That's huge for our product, given it runs in an inherently error-prone environment.
