Java is evolving to incorporate concepts popularized by Rust, such as immutable data structures by default and algebraic data types. These changes were inspired by Rust's emphasis on compile-time safety guarantees. Developers can now define immutable records in Java. Java's new sealed interfaces and exhaustive switch syntax enable the use of algebraic data types so that code handles all possible states of a variable in a type-safe manner.

The debate between using threads and async/await in Rust revolves around simplicity, performance, and composability. While threads may offer familiarity and straightforwardness, async/await is better in I/O-bound scenarios due to its composable code.

This is a long collection of thoughts and problems that two indie developers faced when trying to use Rust for game development after completing development of several games written in Rust. They conclude that Rust presents fundamental challenges to game development, even after one becomes experienced with it. For example, Rust's borrow checker often requires code restructuring for even basic tasks, leading to a frustrating development experience. Also, Rust's focus on refactoring and correctness can lead to over-engineered solutions that prioritize code purity over being able to ship the game to a playable state quickly.

Microsoft has donated $1 million to the Rust Foundation to support the language's infrastructure and fellowship program and to help ease the workload of maintainers.
