rustrust string book

Rust strings are a powerful data type that allow for efficient storage and manipulation of text. They are stored as a sequence of bytes, and can be manipulated with a variety of methods. The Rust Book provides a comprehensive overview of Rust strings, including how to create, manipulate, and convert them.

Example code

let mut s = String::new();

s.push_str("Hello");
s.push(' ');
s.push_str("world!");

println!("{}", s);

Output example

Hello world!

The code above creates a new string, s, and then pushes the strings "Hello" and "world!" onto it. Finally, it prints the resulting string.

The String::new() method creates a new, empty string. The push_str() method adds a string slice to the end of the string, and the push() method adds a single character.
