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

Some of the core methods are discussed in this lesson. You can find a list of all the String methods in [Rust documentation of Strings](https://doc.rust-lang.org/std/string/struct.String.html).

## Capacity in Bytes
The `capacity` gives the number of bytes allocated to the String, unlike `len` which gives the number of bytes taken by the String object.
To get the capacity of a variable in **bytes**, use the built-in function `capacity()`.
### Syntax
The general syntax is:

 `str.capacity()`

Here `str` is the string whose capacity is to be found.

>**Note:** The length of String will always be less than or equal to the capacity.
