const-semver

Const construction of semver-compatible version structs in Rust.

It's simply a const clone of Steve Klabnik's semver crate, with some utilities for converting between them.

Primary use case is for defining const Version strings at compile-time, for example:

```rust use const_semver::{Version, version};

trait Resource { const VERSION: Version; }

struct MyResource {}

impl Resource for MyResource { const VERSION: Version = version!(1,2,3-beta.4+amd64) } ```
