Module version 

Semantic Versioning 2.0.0: parsing, precedence, bumps and Cargo-style requirements.

Version is a strict semver version (with a lenient parser for v1.2), VersionReq a requirement such as ^1.2 or >=1.0, <2.0 using Cargo’s rules, and compare / satisfies are the one-line versions for strings. Bad input is a typed error, never a guess.
