rustrust string byte length

The byte length of a Rust string can be determined using the .len() method. This method returns the number of bytes in the string.

Example

let my_string = "Hello World!";
let byte_length = my_string.len();
println!("The byte length of '{}' is {}", my_string, byte_length);

Output example

The byte length of 'Hello World!' is 12

The .len() method is part of the std::string::String type. It takes no arguments and returns the number of bytes in the string.
