How does it handle multiple potential outcomes? Example: unformat!("a {} b {} c", "a x b b y c") Would it return Some(("x b", "y")) or Some(("x", "b y"))?

I love the concept! I recently wanted something just like this for a Flutter app I was making to parse a filename into a user defined format i.e.

2024-04-12.txt with %Y-%M-%D.txt to {year: 2024, month: 04, day: 12}

I'll certainty be using this the next time I need anything like that in Rust though.

Off-topic, but I recognise your name. Thank you for the Daily Diary App! I'm a huge fan, I use it every day for my gratitude routine.

Wow, I've never had anyone recognise my name for something I've made! Thank you so much and I'm glad you're enjoying it 😁

That's just brilliant.

That’s really clever. I want to use it even though I haven’t been Rust‘ing lately

What am I missing? Seems like it just puts the parameter in Some?

You must've read that wrong.

The first example, but formatted differently:

let value = "My name is Rho.";
let result = unformat!("My {} is {}.", value);

Now, result contains:

Some(("name", "Rho"))

...because the words "name" and "Rho" in value happened to be at the position of the {}-slots in the unformat!()-pattern.

Oh yeah! Thanks. It's been a long day.
