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.

Solution

  • 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\nline two" (of course one can use the \n 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\n\
              lines\n\
              with\n\
              indentation";

    It's the same as "multiple\nlines\nwith\nindentation";
