Rust is a great language, but right now I can start a project in Go and have someone else start a project in Go and have something up and working in a week. Rust still takes significantly longer to learn and/or find skilled developers for. Go is up there with Python in terms of "Get something out now".

Could you explain to a junior what Box<dyn std::error::Error + Send + Sync + 'static> does and how should a person who is starting to learn Rust come up with something like this?
Second minor example. I have a configuration string like let's say timeout for a certain type of connection. What is the recommended way to have that as a string that is accessible to all functions without fighting with the borrow checker?
In Elixir, I would use @timeout in the module for example. In Rust, I am not sure. Cloning the value to every place it needs it as a workaround.
It's like people using `std::string` and not necessarily caring for years what `template<class CharT, class Traits = std::char_traits<CharT>, class Allocator = std::allocator<CharT>> class basic_string;` means or does.
For the second example: environment variable. Once you need more, you can start researching static cells and use a ready crate for configuration loading / processing. If you want more, googling "rust mutable global configuration" brought me https://stackoverflow.com/questions/27791532/how-do-i-create... which gives a pretty good solution.
I guess that time will never come...unless Go somehow looses its way
Before downvoting, this is our experience.
Even in a globalized developer market a smaller developer force is a risk.
In German we have a saying "to die in beauty" (in Schönheit sterben), does that translate? Your boss wants to get things done in due time and I see Go outcompete Rust in this respect.
It does, and it's very evocative.
