The point of this article is just to share my idea.</p> <p>Exception is a popular feature in many programming languages. Unlike Rust where errors are considered as a return value of the <code>Err</code> case of <code>Result</code>, in these languages errors are thrown like <code>panic</code>. The caller may catch the errors and process them similar to <code>catch_unwind</code> in Rust. Different people may have different preferences on the error handling style, but panic-unwind is always considered a bad practice and should be avoided if possible. So using exception-like error handling in Rust is impossible.</p>
