Crate indentkit 

indentkit — detect and convert indentation

Figure out whether a string is indented with tabs or N spaces, and re-indent it from one style to another. Like Node’s detect-indent, but with conversion built in — and zero dependencies, #![no_std].

use indentkit::{detect, reindent, IndentStyle};

let code = "fn main() {\n  println!(\"hi\");\n}\n";
assert_eq!(detect(code), IndentStyle::Spaces(2));

let tabbed = reindent(code, IndentStyle::Tabs);
assert_eq!(tabbed, "fn main() {\n\tprintln!(\"hi\");\n}\n");

Great for formatters, linters, code generators, and editor tooling.
