Unable to match version range with pre-releases

[Wiezzel]

I am trying to match all versions >=1.0.0 and <2.0.0, including pre-release versions. Unfortunately, >=1.0.0-rc, <2.0.0-rc1 doesn't do the trick, as pre-releases only match if some comparator has exactly the same major, minor or patch. Is it even possible to specify this kind of dependency?

I'm having a similar issue, I have a version req that is >=1.0.0, <1.1.0, version that is 1.0.0-beta.6 and apparently the version does not match.
Is there a way to make the VersionReq accept pre-releases?

@gabrik
I have implemented this custom matching logic:

fn version_matches(version: &semver::Version, req: &semver::VersionReq) -> bool {
    if req.matches(version) {
        return true;
    }

    // This custom matching logic is needed, because semver cannot compare different version with pre-release tags
    let mut version_without_pre = version.clone();
    version_without_pre.pre = "".parse().unwrap();
    for comp in &req.comparators {
        if comp.matches(version) {
            continue;
        }

        // If major & minor & patch are the same, this means there is a mismatch on the pre-release tag
        if comp.major == version.major
            && comp.minor.is_some_and(|m| m == version.minor)
            && comp.patch.is_some_and(|p| p == version.patch)
        {
            return false;
        }

        // Otherwise, compare without pre-release tags
        let mut comp_without_pre = comp.clone();
        comp_without_pre.pre = "".parse().unwrap();
        if !comp_without_pre.matches(&version_without_pre) {
            return false;
        }
    }
    true
}

I see, I think I'm going to do the same thing, thank you @Wiezzel

There is another version range does not seems to work: >=0.7,0.8.0-alpha,<0.9 matches 0.8.0-rc1 and 0.8.1 but does not matches 0.7.1.
