Set rust-version to 1.76 & add matrix for building and testing for MSRV

[elpiel]

closes #166

[thejpster]

exclusive range pattern syntax is experimental

oops. Should be easily fixable.

[elpiel]

Yeah, they are easy to fix.
Will get to that.

[elpiel]

I fixed the pattern matching but this trim_ascii_end is giving me a headache.
Any ideas how to replace it?

[thejpster]

You could just copy/paste the source code from the newer library:

impl VolumeName {
    pub fn name(&self) -> &[u8] {
        let mut bytes = &self.contents[..];
        while let [rest @ .., last] = bytes {
            if last.is_ascii_whitespace() {
                bytes = rest;
            } else {
                break;
            }
        }
        bytes
    }
}

[elpiel]

Yep, that should do the trick.
I think I initially just used &self.content which didn't work.

Checks are passing now 🎉

[thejpster]

Yeah because Volume Names are padded with space characters.

The build tasks have been renamed so CI is sad because the job it wants to see didn't run.

The configuration for which jobs are mandatory should be in git, but it's not. It's hidden in GitHub's proprietary back-end.
