pkg-version 0.1.0

Macros expanding to the package version
Documentation
//! Provides macros for fetching the Cargo package version at compile time.
//!
//! All macros defined by this crate return constant expressions, so they can be used inside
//! `const fn`s or to initialize the value of a `const` or `static` item.
//!
//! # Example
//!
//! ```
//! use pkg_version::*;
//!
//! const MAJOR: u32 = pkg_version_major!();
//! const MINOR: u32 = pkg_version_minor!();
//! const PATCH: u32 = pkg_version_patch!();
//!
//! fn main() {
//!     let version = format!("{}.{}.{}", MAJOR, MINOR, PATCH);
//!     assert_eq!(version, "0.1.0");
//!
//!     println!("I am version {}", version);
//! }
//! ```
