This crate provides macros (`pkg_version_major!`, etc.) that expand to the Cargo
package version, as an integer literal.

Previously, the only way to access the package version was by using
`env!("CARGO_PKG_VERSION_MAJOR")` etc., but doing that always results in a
*string* literal, which can only be parsed into a number at runtime. This crate
fixes that problem by parsing the version during macro expansion.

Please refer to the [changelog](CHANGELOG.md) to see what changed in the last
releases.

## Usage

Add an entry to your `Cargo.toml`:

```toml
[dependencies]
pkg-version = "1.0.0"
```

Check the [API Documentation](https://docs.rs/pkg-version/) for how to use the
crate's functionality.
