   • Introduction to Rust Programming Language

     Rust is a blazing fast and memory-efficient static compiled language with a rich type system and ownership model. It can be used to power performance-critical services while guaranteeing memory-safety and thread-safety, empowering developers to debug at compile-time. In addition to that Rust has great documentation and a user-friendly compiler with top-end tools like integrated package managers and multi-editor with features like type inspection and auto-completion. Rust prevents all the crashes, and it is very interesting that rust is safe by default like JavaScript, Ruby, and Python. This is much more powerful than C/C++ because we cannot write the wrong parallel code you can never see fault in rust. It is very fast in representing a lot of programming paradigms very well. 

     <img alt="Introduction-to-Rust-Programming-Language">

     But the question arises as there are already so many programming languages like Python, C++, Java, etc, then why the need for developing a new programming language? The answer to this is the other programming languages have a lot of control over the hardware that you are running, like, you can optimize it well, translate directly to assembly code, but it’s not very safe.

     So rust...

   • Palindrome code in rust programming language

     Top Answer

     Answered Sep 25, 2023 · 1 votes

     The problem is that the .read_line() function does not remove the \n that you entered at the end of inp. You could remove it from the string using pop or use the .trim() method on the String to strip out any newline or whitespace characters at the beginning or end.

     inp = inp.trim().to_string();-

     Just some more improvement on your code, you should leverage Rust's iterators to reverse the String faster rather than manually doing it.

     You can write this:-

     let rev = inp.chars().rev().collect::<String>();-

     This iterates over all the characters in the inp string and reverses them in order. Finally it collects them into a String that is stored in the rev variable.

     Also, you should use == rather than using the .eq() operator, it's just much more clearer.

   • Programming language besides Tcl where everything is string

     Rexx (Restructured Extended Executor) and OORexx are two languages with the same philosophy:

     In Rexx -- somewhat like in TCL -- to a large extent everything is a string. Having stacks and streams composed of lines gives you a simple list or array of strings. But mostly, strings simply act like other datatypes as needed. For example, a string that contains a suitable representation of a number (digits, decimal, an exponent "e", etc.) can be used in arithmetic operations. For processing reports, log files, and the like, this is exactly the behavior you want.

     *nix has many such mini-languages. For example:

     • sed
     • tr
     • cut
     • paste
     • join
     • fmt
     • split
     • pr
     • fold

   • Programming language for functional parallelism: F# vs Haskell

     Top Answer

     Answered May 23, 2017 · 52 votes

     If the kind of code you have in mind allocates memory heavily, then you might find that the GHC garbage collector scales better than the .NET garbage collector. There's some anedcodal evidence that the .NET GC becomes a bottleneck when multiple threads are allocating heavily, and this is also a thorn in the side of most Java collectors too. On the other hand we've paid quite a lot of attention to achieving good locality and scalability in the GHC garbage collector - mainly because we have no choice, most idiomatic Haskell code allocates heavily anyway. I have benchmarks that allocate like crazy and keeping scaling beyond 24 cores.

     In Haskell note that you get a guarantee of determinism from the type system, which you don't get in F#.

     You mentioned Data Parallel Haskell: a cautionary note here, it isn't ready for production use at the present time, although the DPH team are expecting that the forthcoming GHC 7.2.1 release will have a stable DPH implementation.

   • I can't understand the Rust "scope" definition (Rust Programming Language, 2nd Ed. Klabnik & Nichols)

     Top Answer

     Answered Nov 04, 2023 · 3 votes

     There are actually three different scopes. A block's scope, a variable's scope, and a reference's referent's scope.

     A block (curly braces, { ... }) creates a scope. This scope means the variable declared (directly) inside the block will live until its end. A function also creates a scope, in the same way.

     A variable's scope is basically its liveness - where it is alive. It is usually from its declaration until the end of the block (or the function) it is declared in. However, a variable may be moved or dropped and then its life will end before or after the block. Whether its scope ends there or at the block's end (and the value's liveness is longer/shorter) is up to a debate.

     So when the book says:

     A scope is the range within a program for which an item is valid.

     "scope" here refers to the variable's (item's) scope.

     And when it says:

     The variable is valid from the point at which it's declared until the end of the current scope.

     "scope" here refers to the block's scope.

     The third scope is a reference's scope, which the book refers to in pg. 75. Usually, a reference's scope is the same as the scope of the item it refers to, but because of Non-Lexical Lifetimes, it may end earlier, after the reference's last use. This impact when other references to the same item can be used, due to Rust's borrowing rules (shared xor mutable).

     Regarding your questions:

     Is the definition of "scope" different for a variable defined within a function vs. a parameter passed to that function?

     Both are in the function's scope (if the variable is not declared inside an inner block) . Variables defined in the function are dropped before parameters, though, so we can argue their scope ends earlier.

     Is the scoping handling for references different than for other variables?

     Not exactly, but they are considered no longer alive after their last use and not when their block ends. This is not unique to references, however, this is true for any variable that does not have a drop glue.

     When a function param or a variable declared within a function goes out of scope before the end of the function, is the variable's storage released at that time? I.e. prior to the function's return to caller?

     It depends on how you define "memory released".

     The only guarantee Rust makes is that after returning from the function, the stack pointer will be the same as before entering it. Usually, it is only decreased when the function returns, to do it at once instead of many times and save CPU time.

     Another guarantee Rust makes is that Drop is called deterministically. A variable's Drop is called at the end of its block scope, unless it was moved from. So resources owned by the variable (such as heap allocations) are released there.

     Whether the stack memory of the variable is released depends on how you define this. Sometimes the compiler can reuse the stack memory of variables if their lifetimes are not overlapping. Other times it does not, but it will not get used after the variable's scope ends.

   Why is rust used in programming?

   • To simultaneously enforce memory safety and prevent data races, its "borrow checker" tracks the object lifetime of all references in a program during compilation . Rust was influenced by ideas from functional programming, including immutability, higher-order functions, and algebraic data types. It is popular for systems programming.
