Rust is a programming language that offers the performance of C and C++ but with safeguards to stop developers from shooting themselves in the foot. Rust is a modern systems-level programming language designed with security in mind. It provides generics, functional features, zero-cost abstractions, and plenty more. The Rust Programming Language has 125 repositories obtainable. Follow their code on GitHub. The Rust Programming Language (Covers Rust 2018) is the official hands-on, from the Rust developers and no-nonsense guide to learning Rust, at Mozilla. It began as an individual project by Mozilla employee Graydon Hoare and over 5 years grew to become an open-source project accepting contributions from 100 volunteers.

  • Concurrent computing
  • Functional programming
  • Generic programming
  • Structured programming

3) Enlist some advantages of using rust programming?

Some advantages of using rust programming are:

  • Rust Solves Memory Management Problems
  • Rust's Low Overhead Makes It Ideal for Embedded Programming
  • Rust Facilitates Powerful Web Application Development
  • Rust's Static Typing Ensures Easy Maintainability
  • Rust Has Fast and High Performance

4) How do we read a file in Rust?

We can read a file in Rust by:

  • using the read_to_string()
  • using the lines() iterator
  • using the read_line() function

5) How to get install version of rust?

Rust is installed and managed by the rustup tool.

6) What is gdb and lldb in Rust?

GDB and LLDB are the debuggers supporting tool in the Rust compiler that is used to test and debug the "target" program.

7) Is it possible to cross compile in rust?
