Parsing the whole string

[Alice Carroll]

AFAICS the macro searches for a match anywhere in the string provided, which allows "x{}y" to match not only "xAy" but also things like "BxAyC". Is it possible to disable that behaviour, like using ^$ with regex?

Can you write up an MVP to showcase this problem?

[Alice Carroll]

Sure, this is what I would expect:

use unfmt::unformat;

fn main() {
    assert_eq!(unformat!("({:u8}, {:u8})", "(1, 2)"), Some((1, 2)));
    assert_eq!(unformat!("({:u8}, {:u8})", "(1, 2)bar"), None);
    assert_eq!(unformat!("({:u8}, {:u8})", "foo(1, 2)bar"), None);
}

We have an undocumented full match feature which will fix this. I just haven't updated the documentation, but it's there. Just add true as another argument.

Cool, thank you!
