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

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 😁
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.
That's just brilliant.
