In this post, I’ll cover four surprising limitations of the borrow checker that I ran into in the course of my work.
Also note that when I say something can’t be done, I mean that it can’t be done in a way that leverages Rust’s type system, i.e. with static type checking. <...>. It’s never the case that you literally can’t solve a problem at all, since there are always those escape hatches (and I’ll even show examples of an escape hatch I used below), but it is impossible to solve the problem in a way that makes Rust Rust.

Markets continued to grapple with the economic and corporate earnings implications relating to the Russia-Ukraine conflict. “We have a ton of uncertainty right now,” said Stephanie Link, chief investment strategist and portfolio manager at Hightower Advisors. “We’re dealing with a war, we’re dealing with inflation. We don’t know what it means to earnings.” One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. Oleksandra Matviichuk, a Kyiv-based lawyer and head of the Center for Civil Liberties, called Durov’s position "very weak," and urged concrete improvements. Some people used the platform to organize ahead of the storming of the U.S. Capitol in January 2021, and last month Senator Mark Warner sent a letter to Durov urging him to curb Russian information operations on Telegram. Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels.
