pub fn ensure_libxml_init()Expand description
Initialize libxml2 for thread safety. Must be called before any libxml2
operations that don’t go through libxml::parser::Parser. Delegates to
the safe wrapper in rust-libxml, which uses its own std::sync::Once to
guarantee exactly-once initialisation even across threads.
