This course provides the best approach to learn Rust, starting from the basics and advancing to complex topics. It is an introduction to Rust for beginners aspiring to become skilled Rust developers.

The word is out: developers love Rust. It's rapidly becoming a top choice for systems and embedded programmers, and the demand for Rust developers is rising. Known for its performance, reliability, and productivity—especially compared to C++—Rust is a powerful language to master. If you're a systems developer, it's a fantastic next step.
In this course, you'll learn Rust by actively engaging in coding. You’ll start with a simple "Hello world" program and cover essential concepts like arrays, strings, vectors, enums, structures, traits, generics, functions, and logic. You'll also dive into advanced topics such as lifetime and memory management.
By the end of this course, you'll have a solid foundation in Rust programming and be well-prepared to take on more advanced concepts, making it ideal for Rust beginners looking to become proficient Rust developers.

Rust Programming Language

An existing string can be updated by appending a character or a string. 

> **💡** **Why not make a new String rather than updating an existing one?**
>
> Updating an existing String is useful when you want to make changes to an existing String at run time rather than compile one like, in situations where changes are made to the String on a condition.

# Push a Single Character

There are cases when it is required to update a string by pushing a single character. One example is to create a string which contains a single character repeated N times on a particular condition. Rust helps you do it by using the `push`  method.

**Steps to push a character to a String:**
* Make a mutable string variable.
* To push a single Unicode character to a String object, pass a character within the `push()` built-in method.

  The following code shows how to do it!

This lesson will teach to update a string in Rust.
