Constant used in template is not parsed properly

[wezm]

I have a constant:

pub const TOKEN_VALIDITY_DURATION: Duration = Duration::minutes(10);

Which I import and use in a template like:

@use crate::web::password_reset::TOKEN_VALIDITY_DURATION;

@(username: &str, link: &str, new_reset_link: &str)
    ⋮
    <p>
        If you don't use this link within @TOKEN_VALIDITY_DURATION.whole_minutes()
    ⋮

This results in generated code:

TOKEN_.to_html(_ructe_out_)?;
_ructe_out_.write_all(b"VALIDITY_DURATION.whole_minutes()")?;

I think the issue might be the second part of rust_name does not include uppercase letters. I tried adding them and it fixed the problem. I can submit a PR with the changes if you like.

ructe/src/expression.rs

Lines 54 to 62 in 4065b75

	pub fn rust_name(input: &[u8]) -> PResult<&str> {
	map_res(
	recognize(pair(
	alt((tag("_"), alpha1)),
	opt(is_a("_0123456789abcdefghijklmnopqrstuvwxyz")),
	)),
	input_to_str,
	)(input)
	}

Thanks! Yes, your diagnosis seems correct to me, a PR would be great!

(Or I could fix it myself if you no longer have time, since my answer is a week late).

I can do it. I've been using a fixed version in my project. I just need to write some tests to open the PR.
