Struct EscapeAttrValue 

pub struct EscapeAttrValue<T: ?Sized> { /* private fields */ }

Escapes <, &, >, ', " when it appears in the formatted string.

Examples

#[track_caller]
fn check(input: &str, escaped: &str) {
	let mut buf = String::new();
	let mut writer = format_xml::EscapeAttrValue::wrap(&mut buf);
	writer.write_str(input).unwrap();
	assert_eq!(buf, escaped);
}

check("", "");
check(" ", " ");
check("&", "&");
check(" &", " &");
check("& ", "& ");

check("hello", "hello");
check("'world'", "'world'");
check("pre<script>post", "pre&lt;script&gt;post");
check("&<>\"\'", "&amp;&lt;&gt;&quot;&apos;");
check("&a'b<c>", "&amp;a&apos;b&lt;c&gt;");
