rust - What is the syntax for a multiline string literal?

I'm having a hard time figuring out how string syntax works in Rust. Specifically, I'm trying to figure out how to make a multiple line string.

All string literals can be broken across several lines; for example:

let string = "line one
line two";

is a two line string, the same as "line one line two" (of course one can use the newline escape directly too). If you wish to just break a string across multiple lines for formatting reasons you can escape the newline and leading whitespace with a ; for example:

let string = "one line 
    written over 
    several";

is the same as "one line written over several".

If you want linebreaks in the string you can add them before the :

let string = "multiple

              lines

              with

              indentation";

It's the same as "multiple lines with indentation";
