We adopted `askama_escape` with the other askama crates. It was not updated for quite some time, but still gets 25k+ downloads / day Mon to Fri. This PR re-adds the crate using our current HTML escaping function.
askama_escape: HTML escaping, extracted from Askama
Useful if you don't need a template engine, but if you need to escape a text for HTML or XML.
This implementation escapes '"', '&', '\'', '<' and '>'.
Example
use askama_escape::{escape, escape_html, escape_html_char, Html};
assert_eq!(
escape("<script>alert('Hello & bye!')</script>", Html).to_string(),
"<script>alert('Hello & bye!')</script>",
);
let mut dest = String::new();
escape_html(&mut dest, "<script>alert('Hello & bye!')</script>").unwrap();
assert_eq!(
dest,
"<script>alert('Hello & bye!')</script>",
);
let mut dest = String::new();
escape_html_char(&mut dest, '&').unwrap();
assert_eq!(dest, "&");
