2025 Rust Programming for Beginners

Learn how boolean expressions in Rust evaluate to true or false, using x = 7 and condition = x > 5, and print the result as true.

Learn how to write if statements in Rust, covering syntax, conditions, and blocks with practical examples. See x-based scenarios and a main function using println to display outcomes.

Explore how the if else statement works in Rust, including condition evaluation and the if and else blocks, with a sample using x = -2.

Write a Rust program that checks if a number is even or odd using the main function, modulo two, and an if statement to display the result.

Describe the rust if else if ladder as a multi-way selection using if, else if, and else blocks to test conditions in order and execute the first true block.

Implement a Rust program that uses an else-if ladder to check whether a given number is positive, negative, or zero.

Learn to use Rust to find the maximum of two numbers with if else, then extend to three numbers with a ladder of if, else if, and print the max.

Rust looping with loop, while, and for constructs to run code repeatedly. Learn to terminate loops with break using a counter to print hello ten times.

Learn the rust while loop: its syntax, a mutable counter, and how the loop runs until the condition is false, with an example printing 1 to 5.

Implement a Rust while loop to print numbers from 1 to n using a mutable counter, updating i and printing each value until n is reached.

Rust code uses a while loop to compute the factorial of a number, multiplying a mutable f by i from 1 to n and printing the result (120 for n=5).

Master the rust for loop to iterate over a numeric range. Understand the start inclusive and end exclusive behavior, using start..end with a print statement to display 1 to 5.

Learn to compute the sum from 1 to n in Rust with a for loop and a mutable accumulator, noting the end bound is exclusive.

Define arrays in Rust as lists of elements with the same data type, created with explicit type, inferred type, or default values via repeat expressions.

Learn how to define and modify a mutable array in Rust with let mut, because arrays are immutable by default; change an element by index and see the updated output.

Find the length of an array in rust using the array alien method. Display the length with the println macro for arrays of any type.

Learn to loop through a Rust array with a for loop and index, display each index and value with println, and compute the array length to iterate over days.

Compute the sum of array elements in Rust using a mutable accumulator and a for loop, demonstrated with 10, 20, 30, 40, 50 totaling 150.

Find the maximum and minimum in an array by using a mutable max and min initialized to the first element, updating on each comparison, and printing the results.

Learn to create and mutate a mutable slice in Rust with the mut keyword and a reference; see how changing an element updates the slice and the original array.

Learn how to create and use tuples in Rust to store different data types in a fixed-size structure, explore creation methods—with data type and without data type—and printing with println.

Access tuple elements using a tuple index and dot notation, as shown with t = (hello, 200, 5.75). Retrieve t.0, t.1, and t.2 to print each value.

Learn how to create and modify a mutable tuple in Rust using the mute keyword, access elements by index with the dot operator, and print the updated tuple.

Destructure a tuple in Rust by binding each element to separate variables, using (name, age, height) = tuple, with examples like John, 23, 178 and Hello world, 16, 2.71828.

Explore functions in Rust by defining functions with the fn keyword, passing arguments, calling them from main, and using the println macro to display results, such as summing two numbers.

Write a Rust function to check parity using number % 2 == 0, returning a boolean and printing whether a number is even or odd, with examples.

Learn to return multiple values from a Rust function by implementing add_sub that yields sum and difference as i32, with an example using 4 and 1.

Explore how variable scope works in Rust by showing how variables defined in a block stay within that block, while outer variables remain accessible inside inner blocks and not outside.

Explore closures in Rust, also known as anonymous functions, and learn to declare, bind to a variable, and call them to compute values like x plus one.

Define a structure in Rust with the struct keyword to group name (string), age (u8), and height (u8) into a single unit and avoid separate variables.

Define a person struct with name, age, and is_student fields and their string, unsigned integer, and boolean types. Instantiate person_one in main and access fields with dot operator to print.

Learn to destructure a Rust struct named person into name, age, and student fields and print each field with the println macro.

Explore how vectors work in Rust, a resizable data structure that stores elements of the same type, created with the vec macro, and accessed by index.

Learn how to add values to a mutable vector in Rust with push, appending 12, 14, and 16 to an even-number sequence, and display the updated vector.

Learn to iterate through a vector in Rust using a for loop with an index range, accessing each element by index and printing its value, demonstrated with a six-color vector.

Learn how to remove a value from a Rust vector via the remove method by index, illustrated by a 2,4,6,8,10 sequence becoming 2,4,6,10 and then 2,6,10.

Learn to create strings in Rust using String::from, print the value, and make a mutable string to append new text with push_str, showing the updated string.

Explore string slicing in rust by creating a string, selecting a start and end index, and printing both the original string and the resulting slice.

Iterate over strings to print each character using the chars method, then create an empty string with new, and append rust coding to show the updated content.

Explore Rust's ownership rules to ensure memory safety by assigning a single owner per value, transferring ownership between bindings, and dropping values at scope end.

Explore how primitive types in Rust use copy semantics, allowing data to be copied from x to y without affecting ownership, keeping x usable while preventing memory leaks and slowness.

Explore ownership in Rust functions, showing how heap data types like strings move ownership when passed to a function, while static only types such as integers are copied.

Explore how references borrow ownership in Rust by passing values to functions without transferring ownership, using ampersands and &str to view strings safely.
