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> https://jason5lee.me/blog/rust-costumized-trait-object/ Sat, 11 Jan 2020 21:03:30 +0000 https://jason5lee.me/blog/rust-costumized-trait-object/ <p>I love the traits in Rust language. Rust uses one mechanism for both compile-time polymorphism and runtime polymorphism, which is elegant. However, the runtime polymorphism in Rust is not very flexible. Some traits cannot be used as a trait object, and it&rsquo;s impossible to specify whether a method is resolved dynamically or statically. This shortage is reflected in my recursive function library <a href="https://github.com/Jason5Lee/rust-recur-fn">RecurFn</a>, and I develop a workaround, calling it <strong>customized trait object</strong>.</p>
