Function textwrap::indent[][src]

pub fn indent(s: &str, prefix: &str) -> String

Add prefix to each non-empty line.

use textwrap::indent;

assert_eq!(indent("
Foo
Bar
", "  "), "
  Foo
  Bar
");

Lines consisting only of whitespace are kept unchanged:

assert_eq!(indent("
Foo

Bar
  \t
Baz
", "->"), "
->Foo

->Bar
  \t
->Baz
");

Leading and trailing whitespace on non-empty lines is kept unchanged:

use textwrap::indent;

assert_eq!(indent(" \t  Foo   ", "->"), "-> \t  Foo   ");
