This update of Arbitrum @arbitrum Stylus Rust SDK v0.9 is, to be honest, of great significance. For a long time, Rust has been hailed as the "king of performance," but when it comes to the field of smart contracts, the high entry barrier, inadequate tools, and lack of basic features like constructors have deterred many developers. Now, @Arbitrum has broken through this barrier with a key update. The addition of constructors is not just about filling a functional gap; it represents a fundamental upgrade to the development experience. It allows Rust smart contracts to truly become production-ready and mature. What I appreciate most about this change is the signal it sends: Arbitrum is not just looking to be an "Ethereum-compatible extension" but aims to create an ecosystem for the next generation of high-performance developers. The introduction of Rust allows smart contracts to move beyond the paradigm of Solidity and enter a higher level of engineering thinking—safer, faster, and more controllable. This also means that future dApps may no longer be a combination of "Ethereum logic + L2 extension," but rather a new combination of "Rust engineering + Arbitrum performance." For teams pursuing extreme execution efficiency, privacy, and security, this marks the starting point of a new era. So, if you are still on the fence about whether the combination of Rust and Arbitrum @arbitrum is worth trying, my answer is: this is not a trend, but an inevitability. Constructors are just the beginning; the true Rust era has only just begun. #arb
