pub fn init_parser()Expand description
Ensure libxml2’s global parser state is initialised. Safe to call from
any number of threads — internally guarded by std::sync::Once so the
underlying xmlInitParser() runs exactly once. Call this before
performing any libxml2 operations from application code that does
not go through the parser::Parser API (which initialises lazily).
See libxml2’s own thread-safety guidance: https://dev.w3.org/XInclude-Test-Suite/libxml2-2.4.24/doc/threads.html
