When comparing Rust vs Dart, the Slant community recommends Dart for most people. In the question“What are the best languages for writing command line utilities?” Dart is ranked 8th while Rust is ranked 9th. The most important reason people chose Dart is:
Dart is a single threaded programming language. So if any piece of code blocks the execution of the program, the program practically freezes. To avoid this Dart makes use of asynchronous operations which let your program run without getting blocked. This is done through Future objects. A Future is an object which represent a means for getting a value at a certain point in the future. A function may invoke a Future and when that happens, two outcomes can be achieved: 1. The function is unable to return a value, so it queues up work to be done and returns an uncompleted Future object. 2. Or later when a value is available to be returned, the Future object completes with that value.

Pros
Pro Non-PvP servers are available
If worrying that another player might kill you and loot your corpse is not your thing, or if you don't want to deal with someone constantly harassing your base, there are servers available that take away the risk of other player's malicious behavior.
Pro Building system is simple, efficient and intuitive
Hold a key while holding a hammer, and with your cursor, select the piece you want to build.
Upgrading a piece of building is done in the same fashion.
Pro Game's multiplayer nature creates psychological tension
While there's obviously potential for working together with other players towards achieving certain goals, the more likely scenario is someone trying to kill you to get your stuff. Or even worse, deceiving you in working together to achieve a particularly difficult goal only to stab you in the back when you're not needed anymore. It's easier to take stuff from someone else than gather it yourself. And since your base is a the perfect bullseye to other players, there is constant threat of griefing.
Pro Lots of variety in ways to die
Fauna, including bears and wolves, is trying to kill you, radiation, that's ever-present, is trying to kill you, zombies, in a multitude of colors, are trying to kill you, other players on the server, equipped with guns, are most definitely trying to kill you, and you, yourself, if you don't find food, will die.
Pro Base building allows for less punishing gameplay
Because you can build your base that you respawn back to when killed, losing only what you had on you at the time of death, it allows getting back to where you left off quickly.
Pro Great async language support
Dart is a single threaded programming language. So if any piece of code blocks the execution of the program, the program practically freezes. To avoid this Dart makes use of asynchronous operations which let your program run without getting blocked. This is done through Future objects.
A Future is an object which represent a means for getting a value at a certain point in the future. A function may invoke a Future and when that happens, two outcomes can be achieved:
- The function is unable to return a value, so it queues up work to be done and returns an uncompleted Future object.
- Or later when a value is available to be returned, the Future object completes with that value.
Pro Great standard library
Dart includes a truly comprehensive core library, making it unnecessary to include disparate, external resources for basic functionalities Other than reducing the need to pull in various 3rd-party utilities this also ensures that all Dart code looks and feels the same.
Out of the box, the developer gets core libraries to help with: async, collections, strings, regexps, conversions, formats, file I/O, math, typed data, and more.
Pro No compile time in development
Dartium (Chromium derivative) is a browser with integrated Dart VM, which allows you to run and debug native Dart code during development for short edit-reload cycles. Only for testing on other browsers and deployment is transpiling to JS necessary.
Pro A lot of tools are available to help in developing with Dart
Dart has a lot of tools available which help with developing Dart applications. Some examples of those tools include:
- pub - package and dependency management and build tool
- analyzer - static syntax analysis with linter, quick fixes, autocompletion support for easy IDE integration
- test - powerful and flexible testing framework and test runner
- dev_compiler - generate reusable JS instead of tree-shaken minified JS output (work in progress)
- dartfmt_ - source code formatter
- server-side VM
- observatory - a powerful tool for profiling and debugging running Dart code (for Dartium and Dart server code)
Pro Transpiled JavaScript code works on all browsers
In Dart many browser differences (subtle differences and also missing features) are abstracted away or polyfilled. When Dart is transpiled to JS the output works on all supported browsers. There is usually no need to load polyfills or to consider browser differences during development. No need for libraries like jQuery to make the same code work the same on all browsers.
Pro Will be familiar to Java developers
The language will look familiar to Java developers, easing the learning curve.
And yet, while it's similar, it has some nice syntax facilities to avoid common boilerplate code found in Java. Code is terser, yet readable.
Pro Easy prototyping
Dart has an optional type system which makes Dart a great language for prototyping. It encourages developers to gradually evolve their programs without worrying about types first.
Pro Can compile to efficient machine code
Dart was designed to be as expressive as possible. Ahead-of-time compilers can compile Dart code to efficient machine code. This is especially important when deploying to mobile where you don't want (or can't) use a JIT.
Pro AngularDart 2.0 support
Pro Optional strong mode.
Strong mode applies a more restrictive type system to Dart to address its unsound, surprising behavior in certain cases.
Pro Support of semi-coroutines (generators)
Generators, also known as semicoroutines, are also a generalization of subroutines.
Generators are primarily used to simplify the control of iteration behavior of a loop, the yield
statement in a generator passes a value back to a parent routine.
A generator is very similar to a function that returns an array, in that a generator has a certain number of values. But instead of building and returning an array that contains all the wanted values, a generator returns them one at a time, this saves memory and allows the caller function to start processing the first few values immediately.
Pro The Dart to JavaScript compiler generates high quality source code
Dart to Javascript compiler (dart2js) generates very high quality source code with very high optimization. The output code is also very readable and easy to understand.
Pro Crossplatform
Dart does not just compile to JavaScript, it also compiles to native code on mobile platforms like iOS and Android as demonstrated by flutter.io
Cons
Con Hard to play solo
Rust is all about clans fighting for territory and loots. Solo players (or ones with a couple friends) can easily be killed by bigger clans.
Con Not yet finished (buggy)
Since it's a Steam Early Access game it still has lots of glitches, placeholder text and unreliable infrastructure. But for all its unfinished nature, it's surprisingly playable.
Con Doesn’t generate consumable JavaScript at present
Dart builds to JavaScript but the entire app needs to be built to JavaScript at once for now (that may change in the future).
Con Still many holes to fill while converting code to Javascript
While implementing callbacks, passing a type to any function that gets passed to Javascript causes the dart2js compiler to crash.
Con Dart SDK does not provide standard (out of the box) way to access SQL-based databases on server side
This missing (but very popular) feature requires to use 3rd-party packages developed by the personal enthusiasts or very small groups of enthusiasts, which is not very convenient because they are all very fragmented in terms of content, the essence and capabilities.
Con Small community, little momentum
Con May be difficult to use some JavaScript libraries
Dart is much more than a programming language, it's a platform with its own standard libraries and tools. It's a major departure from JavaScript itself (even though it can compile to JS) that it's not possible to directly interact with JavaScript libraries in Dart. Instead, you have to use a special interop library which exposes the wrapped versions of the JavaScript objects that you are accessing.
While this enables Dart to sandbox JavaScript so that its problems do not leak into a Dart application, it also means that it may be cumbersome to use libraries which don't have a wrapper library available.
