Function xmldecl::parse

pub fn parse(bytes: &[u8]) -> Option<&'static Encoding>

Extracts an encoding from an ASCII-based bogo-XML declaration. bytes must the prefix of a text/html resource. If it is longer than 1024 bytes, only the first 1024 bytes are examined.

The intended use is that when the meta prescan fails, the HTML parser will have buffered the first 1024 bytes at which point they should be passed to this function.
