Sized (or Sizeable) str, e.g. str<const N: usize>

kpreid:

macro_rules! sizstr {
    ($text:literal) => {
        SizStr::<{ $text.len() }>::strict_from_ref($text)
    };
}

In a nutshell, that’s the base case of my stringlet!() macro, yes. But I get a feeling that many people don’t like macros. Some crates even hide them in an optional feature. I was wanting to make the functional folks happy as well.

And this indeed seems a valid improvement – thank you:

kpreid:

macro_rules! sizstr {
    ($text:literal) => {
        const {
            const TEXT: &str = $text;
            SizStr::<{ TEXT.len() }>::strict_from_ref(TEXT)
        }
    };
}
