rustversion_detect/
lib.rs

1//! This crate provides a simple API for detecting the rustc
2//! compiler version.
3//!
4//! It is primarily intended for build scripts, but is also usable at runtime.
5//!
6//! The implementation is forked from the [`rustversion` crate], but with proc-macro code removed.
7//!
8//! [`rustversion` crate]: https://github.com/dtolnay/rustversion
9//!
10//! # Dependency
11//! Add the following to your build script:
12//! ```toml
13//! [build-dependencies]
14//! rustversion-detect = "0.1"
15//! ```
