What is the syntax for a multiline string literal?

Question

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.

Huon's answer is correct but if the indentation bothers you, consider using Indoc which is a procedural macro for indented multi-line strings. It stands for "indented document." It provides a macro called indoc!() that takes a multiline string literal and un-indents it so the leftmost non-space character is in the first column.

let s = indoc! {"
    line one
    line two
"};

The result is "line one\nline two\n".

Whitespace is preserved relative to the leftmost non-space character in the document, so the following has line two indented 3 spaces relative to line one:

let s = indoc! {"
    line one
       line two
"};

The result is "line one\n line two\n".
