Enum pep440::PreRelease

pub enum PreRelease {
    RC(u32),
    A(u32),
    B(u32),
}

The pre-release component of a version, such as rcN, bN, or aN.

We don’t implement Ord on PreRelease because the context (Versions) under consideration matter. In other words, 1.2.3b1 < 1.2.3rc1, but 1.2.4b1 > 1.2.3rc1. If we allowed for comparing PreReleases alone, in the first scenario, we would have B(1) < RC(1) and in the second scenario we would have B(1) > RC(1). So we only implement comparison of PreRelease as part of the definition of comparison of Version as a whole.
