I adore unsafe, appreciate it as a feature... but it is an escape hatch. One that is sometimes necessary, one that is sometimes not necessary but might still be (ab)used for performance, or initial 1:1 porting of C/C++ code. There are a lot of cases where that escape hatch should probably welded shut though. Fortunately, the Rust ecosystem has tools like `cargo geiger`, and straight out of the box I can also write:

    // src\lib.rs
    #![forbid(unsafe_code)]
