rustrust string doc


Rust strings are a collection of bytes, and are used to represent text. Strings are immutable, meaning that once created, their contents cannot be changed. The Rust String Docs provide detailed information about the various methods and operations that can be performed on strings.

Example

let mut s = String::from("Hello");

s.push_str(", world!");

println!("{}", s);

Output example

Hello, world!

The example above creates a String called s and assigns it the value Hello. The push_str() method is then used to append the string ", world!" to the end of s. Finally, the println! macro is used to print the contents of s to the console.

The Rust String Docs provide information about the following methods and operations:

  • Creating strings
  • Appending strings
  • Comparing strings
  • Slicing strings
  • Iterating over strings
  • Formatting strings
  • Converting strings to other types
  • Encoding and decoding strings
  • Searching strings
  • Replacing strings
  • Trimming strings
  • Joining strings
  • Splitting strings
  • Copying strings
  • Reversing strings
  • Counting characters
  • Comparing characters
  • Converting characters
  • Encoding and decoding characters
  • Iterating over characters
  • Parsing characters
