thru_base/
version.rs

1//! Version string utilities for thru binaries.
2//!
3//! Provides a macro to generate version strings with git info.
4//! The macro must be used because env vars are resolved per-crate at compile time.

6/// Generate a version string with git info.
7///
8/// Returns format: "0.1.0+abc1234" or "0.1.0+abc1234-dirty"

10/// # Example
11/// ```ignore
12/// use thru_base::get_version;
13/// let version: &'static str = get_version!();
