    Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency, see: https://www.rust-lang.org/. Rust fills a niche between C and C++. It can perform low level hardware interfacing like C while being significantly simpler than C++. It has Foreign Function Interface (FFI) tools that enable it to work w...

    Rust has strict memory ownership rules that enable the Rust compiler to manage memory safely without incurring runtime costs, they include: 1. Each value has a unique owner, a value is dropped whenever its owner goes out of scope. 2. A value can have one mutable reference or multiple immutable references to it at a time. A value cannot have more th...

    If Rust is so safe, why can’t it be used in safety-critical software? Because it hasn’t been certified yet. Unlike bugs in commercial software, which only have a financial cost (Microsoft estimated $250000 per CVE in 2004), bugs in safety-critical software may cause a loss of life. Therefore, safety-critical software must be written to rigorous sta...

    There are very few programming languages that are suitable for developing safety-critical software, especially for real-time and embedded systems. Rust is a popular new programming language that is ideally suited to developing safety-critical software. Rust is not currently used for safety-critical software development because it is not qualified y...

  3. mlua is bindings to Lua programming language for Rust with a goal to provide safe (as far as it's possible), high level, easy to use, practical and flexible API. Started as rlua fork, mlua supports Lua 5.4, 5.3, 5.2, 5.1 (including LuaJIT) and Roblox Luau and allows to write native Lua modules in Rust as well as use Lua in a standalone mode.

  4. I'm glad to announce first mlua version 0.8.0-beta.1 with Roblox Luau support. mlua provides unified high level interface to all Lua versions (5.1-5.4) including LuaJIT and now Luau with simple switch between them using feature flags.

  5. Yes. Type safety is great, but the degree of type safety varies by language. Rust is very type safe, Go somewhat less so (no type parameters, so user-provided collections aren't type safe, or aren't generic). Types are opt-out (or maybe opt-in) in Typescript, because it needs JS interop.

  6. Nov 2, 2022 · Just this week, a high-criticality vulnerability in the ubiquitous secure communication library OpenSSL could have been prevented if the mechanism were written in a memory-safe language.

  7. More accurately, Rust contains both a safe and unsafe programming language. Rust can be thought of as a combination of two programming languages: Safe Rust and Unsafe Rust. Conveniently, these names mean exactly what they say: Safe Rust is Safe. Unsafe Rust is, well, not. In fact, Unsafe Rust lets us do some really unsafe things.
