Utility crate for fast SemVer **like** Versions and Version Requirenments. If you look for full
SemVer experience and/or easy usage, please consider the excellent
[semver](https://docs.rs/semver/latest/semver/index.html) crate.

This implementation however doesn't require allocations, thus can be used in compile time
evaluation. (support for embedded will follow)

### Example
```rust
use fast_version::{Version, VersionReq, VersionReqVariant, const_version};

const VERSION: Version = const_version!("1.2.3");

assert_eq!(VERSION.major, 1);
assert_eq!(VERSION.minor, 2);
assert_eq!(VERSION.patch, 3);

const VERSION_REQ_MATCH: VersionReq = {
    let version_req_variant = VersionReqVariant::Strict(VERSION);
    VersionReq::new(&version_req_variant)
};

assert!(VERSION_REQ_MATCH.matches(&VERSION));

const VERSION_REQ_UNMATCH: VersionReq = {
    let version_req_variant = VersionReqVariant::MajorLessEqual { major: 0 };
    VersionReq::new(&version_req_variant)
};

assert!(!VERSION_REQ_UNMATCH.matches(&VERSION));
```
