## tbisversion-derive

`thisversion-derive` implements the `VersionFamily` and `VersionBoundary`
derive macros used by [`thisversion`](https://crates.io/crates/thisversion).
They connect historical schema types to an application's current model while
keeping migrations explicit and checked by Rust's type system.

Most applications should depend on `thisversion`, which re-exports both
derives, rather than depending on this implementation crate directly:

```toml
[dependencies]
thisversion = "0.1"
```

See the [main crate README](https://github.com/arifd/thisversion) for
usage, examples, and the project guide.
