Hello World Code Gives Scary Warning! about nickel.rs HOT 4 CLOSED

Good catch, the examples on https://nickel-org.github.io/ have gotten out of date. Everything in the examples fixes this by adding unwrap, i.e. server.listen("127.0.0.1:6767").unwrap();. This is ok for examples and cases where that is the last statement in main. Production uses may want more robust logging of the returned Err(e).

I'll keep this issue open until the https://nickel-org.github.io/ pages have been updated.

You could modify your main() function to return a Result<(), Error> and then use server.listen("127.0.0.1:2676")?

Ah, I see. thanks

So am I "losing the errors" when writing it as Some(server.listen("127.0.0.1:6767")); or would it be equivalent in this case server.listen("127.0.0.1:6767").unwrap();?

(or maybe both since returning a plain string can't really fail?)
