//! This build script ensures that Clippy is not compiled with an
|
|
//! incompatible version of rust. It will panic with a descriptive
|
|
//! error message instead.
|
|
//!
|
|
//! We specifially want to ensure that Clippy is only built with a
|
|
//! rustc version that is newer or equal to the one specified in the
|
|
//! `min_version.txt` file.
|
|
//!
|
|
//! `min_version.txt` is in the repo but also in the `.gitignore` to
|
|
//! make sure that it is not updated manually by accident. Only CI
|
|
//! should update that file.

//! This build script was originally taken from the Rocket web framework:
