Anyhow ? Turbofish ::<> / HTTP Calls and Errors in Rust

Rust is a very powerful and full-featured systems language. However, its native idioms (at least in their default implementations) can be quite verbose. Even when you just want to GET a JSON document and do something with it. Explicitly matching every Result case is required to avoid panic. Or is it? Let’s learn together to use turbofish syntax and the anyhow crate to produce more elegant but still idiomatic Rust code that allows us to explicitly handle Result(s) as necessary. We’ll demonstrate making Rest API calls using Rust request and we’ll show how to incrementally minimize the amount of boilerplate it takes.
