Rust provides us with a match keyword that can be used for pattern matching. It is similar to the switch statement in C, and the first arm that matches is evaluated.ExampleConsider the example shown below −fn main() { let number = 17; println!("Tell me about {}", number); match number { 1 => println!("One!") 2 | 3 | 5 | 7 | 11 => println!("A prime"), 13..=19 => println!("A teen"), _ => println!("Ain't special"), } }In the above example, we are trying to use a ...

Handling critical errors in Rust is done with the help of panic! Macro. There are other ways to handle errors in Rust, but panic is unique in the sense that it is used to deal with unrecoverable errors.When we execute the panic! Macro, the whole program unwinds from the stack, and hence, it quits. Because of this manner with which the program quits, we commonly use panic! for unrecoverable errors.SyntaxThe syntax of calling a panic looks like this −panic!("An error was encountered");We usually pass a custom message inside the parentheses.ExampleConsider the code shown below as a reference −fn drink(beverage: &str) ...

Path struct in Rust is used to represent the file paths in the underlying filesystem. It should also be noted that a Path in Rust is not represented as a UTF-8 string; instead, it is stored as a vector of bytes (Vec).ExampleConsider the example shown below −use std::path::Path; fn main() { // Create a `Path` from an `&'static str` let path = Path::new("."); // The `display` method returns a `Show`able structure let display = path.display(); // Check if the path exists if path.exists() { println!("{} exists", display); } ...

Vectors in Rust are like re-sizable arrays. They are used to store objects that are of the same type and they are stored contiguously in memoryLike Slices, their size is not known at compile-time and can grow or shrink accordingly. It is denoted by Vec in RustThe data stored in the vector is allocated on the heap.ExampleIn the below example, a vector named d is created using the Vec::new(); function that Rust provides.fn main() { let mut d: Vec = Vec::new(); d.push(10); d.push(11); println!("{:?}", d); d.pop(); println!("{:?}", d); }We push the elements into a ...

We know that Rust provides a loop keyword to run an infinite loop. But the more traditional way to run loops in any programming language is with either making use of the while loop or the for range loop.While LoopThe while loop is used to execute a code of block until a certain condition evaluates to true. Once the condition becomes false, the loop breaks and anything after the loop is then evaluated. In Rust, it is pretty much the same.ExampleConsider the example shown below:fn main() { let mut z = 1; while z < 20 { ...
