Fix E0700: Unconditional Panic in Rust Compiler

The Rust compiler error E0700 occurs when code paths exist that never return normally because they unconditionally panic. This error signals a fundamental mismatch between what the compiler expects—a function that returns a value—and what the code actually provides—code that terminates execution by panicking without returning.

1. Symptoms

When E0700 is triggered, you will see error output similar to the following:

error[E0700]: unreachable code
  --> src/main.rs:5:5
   |
5  |     unreachable!();
   |     ^^^^^^^^^^^^^^ aid or diverges
   |
   = note: anticipated error from this path

Another common manifestation occurs when using std::process::exit or similar terminating functions:

The go-slice-bounds-out-of-range error is a common runtime panic in Go applications, indicating an attempt to access an element of a slice at an index that does not exist within its current length. This error is a critical safety mechanism in Go, preventing memory corruption and unpredictable program behavior that could arise from accessing memory outside the bounds of an allocated slice. Understanding its causes and systematic debugging is crucial for robust Go development.
