The weird of function-local types in Rust
> To the extent there is an exception, testing-only code may be. Testing-only code has very different constraints than production code anyhow. Even then, though, I still find that refactoring problem arises, and test code needs to be refactorable too.
For me, I avoid defining anything within a function except when that thing being defined is what is being tested in a test, e.g. https://github.com/clap-rs/clap/blob/87647d268c8c27e3298b2c0...

CLI Contexts
I recently came across this question (and associated answer) on the clap repository. The answer given is a good one. But I wanted to expand with my own findings and practices, which spurred the motivation for this post.

Getting Started with CLI tools in Rust using Clap
We can also use tuple-like struct syntax and named-field struct syntax for enum variants within our enum; this is because unlike in other OOP languages, Rust enums are actually sum types. You can read more about how powerful Rust enums are in another article we wrote here. You can have optional arguments by simply wrapping the types in Option, but if you want to add a flag to a command you can use bool, since clap recognises that flags are either there or not there. Let's have a look at what this might look like:

Flow Updater JSON Creator
I began by developing a wrapper for the CurseForge API, which turned out to be a lengthy and challenging process but constituted the bulk of the work. Next, I coded the CLI, which was relatively straightforward. Instead of using the clap crate, a Rust tool for generating CLIs, I opted for the following line of code:

netcrab: a networking tool
By this time I had already gotten tired of parsing arguments by myself and had looked for something to help with that. I found a really dang good argument parsing library called clap. What makes it so cool is it's largely declarative for common uses. You simply mark up a struct with attributes, and the parser automatically generates the usage and all the argument parsing code.
