Which is more efficient: the C, or Rust Programming Language

A comparative analysis of how fast C & Rust languages by using the most well-known sorting algorithm.

The most popular household appliances like microwave ovens washing machines, microwaves, as well as digital camera are getting more sophisticated each day. A microprocessor, operating system, and the software within these devices provide this information. These programs not only require a high level of efficiency and efficiently, but they also need to operate on a limited quantity of memory. It’s not a surprise that these programming languages are written using C. In this Blog, You will know the Which is more efficient: the Rust Programming Language, or C?

The majority of the popular operating systems such as Windows, UNIX, Linux are compose with C. That’s due to the fact that even today , when it regards speed (speed execution) nothing can beat C (but not until the future). Furthermore, if one wants to expand your operating system’s ability to accommodate new devices, it is necessary to create driver programs for devices. The programs are create in C.

C language has had a significant effect on the IT industry, and is still playing an important function.

Features of Rust programming Language

1. Zero cost abstraction

In Rust we can also create abstractions that do not affect the performance of the code. It enhances the code quality and accessibility of the code without a cost to runtime performance.

2. Error messages

When it comes to C++ programming, there is a huge enhancement in the error message in comparison to GCC. Rust takes one step further when it comes to issues of clarity. Error messages are display using (formatting and colors) and may also hint at mistakes in our software.

3. Type inference

Rust offers the benefit of Rust has the feature of Type inference, which is a way of determining the kind of expression automatically.

4. Move semantics

Rust offers this feature that permits a copy operation to be replace with the move operation when the source object is temporary.

5. Threads with no data races

A data race occurs that occurs when more than one thread access an identical location in memory. Rust allows threads not having data races due to the nature due to the system of ownership. The ownership system only transmits the owners of objects belonging to multiple threads. Two threads cannot have the same object with write access.

6. Security of memory guaranteed

Rust made sure that memory security was guarantee with the notion of ownership. Ownership is an intermediate between the control of memory in C as well as the garbage management in Java. In Rust programs memory space is owned by variables, and then temporarily borrow by other variables. This permits Rust to ensure memory security during the compilation time, without relying on an garbage collector.

7. Efficient C bindings

Rust has the ability to provide “Efficient C bindings’, which means the Rust language is capable of interfacing to the C language, as it speaks to its own. Rust offers a ‘foreign function interface’ to connect to C API’s, and use it’s ownership structure to ensure the safety of memory simultaneously.

8. Secure memory space allocation

In Rust memory management, it is a manual process, i.e., the programmer is in control of how memory allocation and allocated. In C language memory allocation, we allocate the memory with malloc function and then we initialize it, however Rust rejects both of these operations with a single operator. This operator changes the smart pointer to integer. Smart pointers are an exclusive kind of value that regulates when an object is release. They are “smart” since they don’t only know the location of objects but also understand how to take it away.

Rust Programming Language could be a contender in all fields

Rust is an multi-paradigm language for programming that is focused on speed and security specifically, secure concurrency. It is syntactically akin with C++, and allows memory safety without garbage collection, but by using an borrowing check system.

Rust initially design by Graydon Hoare from Mozilla Research.

Rust focuses on these things Rust primarily focus on the following things:

1. Concurrency.

2. Safety.

3. Speed.

Memory security

The most important selling point of Rust is the fact that it promises that, when you compile it, your application will not be harm from dereferencing null and dangling pointers. Rust makes it extremely difficult to lose memory.


The Rust language doesn’t have an garbage Collector (GC) in the sense that it is design. Rust will know when a variable is beyond its scope or duration expires at compile time, and then insert the appropriate instructions for LLVM/assembly to free up the memory. This increases the performance during runtime.


In Rust thread can be “isolate” from one another by default, due to ownership. Writing can only occur in the event that the thread is able to access mutable data via ownership of the data or possessing an mutable borrowing of it. Whatever the case the thread will be the sole one to have access at the moment.

Web Assembly Support Web Assembly

It helps to execute high computation-intensive algorithms in the browser, on embedded devices, or anywhere else. Web Assembly runs with the same speed as native. Rust is able to be convert into Web Assembly for fast, efficient execution.

Comparative study of the speed of C and Rust Programming Language


The way to compare the speed of the two languages is to create the most well-known sorting algorithms, and then using them in various element ranges, and then testing which one took the longest time to sort the elements. The sorting algorithm that I’m using is:

1. Bubble Sort.

2. Insertion Sort.

3. Selection Sort.

4. Shell Sort.

5. Heap Sort.

Above is the complexity of time of the most popular sorting algorithms. By looking at the most complex cases we can get an idea of which sorting method would be performing the best among them.

Bubble sort is the most complex of all difficulty in the range of O(N2) and definitely will perform worst when in comparison to other sorts. The matrix that we will be creating can also assist us to determine the complexity at the lowest level with respect to time, by measuring the amount of time needed to sort the components.
