class DebugInfoParser(object, metaclass=_DebugInfoParserMetaClass):
	:py:class:`DebugInfoParser` represents the registered parsers and providers of debug information for Binary Ninja.
	The debug information is used by Binary Ninja as ground-truth information about the attributes of functions,
	types, and variables that Binary Ninja's analysis pipeline would otherwise work to deduce. By providing
	debug info, Binary Ninja's output can be generated quicker, more accurately, and more completely.
	A DebugInfoParser consists of:
	2. An ``is_valid`` function which takes a :py:class:`binaryview.BinaryView` and returns a bool.
	3. A ``parse`` function which takes a :py:class:`DebugInfo` object and uses the member functions :py:meth:`DebugInfo.add_type`, :py:meth:`DebugInfo.add_function`, and :py:meth:`DebugInfo.add_data_variable` to populate all the info it can.
	And finally calling :py:meth:`DebugInfoParser.register` to register it with the core.
	A working example::
		import binaryninja as bn
		def is_valid(bv: bn.binaryview.BinaryView) -> bool:
			return bv.view_type == "Raw"
		def parse_info(debug_info: bn.debuginfo.DebugInfo, bv: bn.binaryview.BinaryView, debug_file: bn.binaryview.BinaryView, progress: Callable[[int, int], bool]) -> None:
			debug_info.add_type("name", bn.types.Type.int(4, True))
			debug_info.add_data_variable(0x1234, bn.types.Type.int(4, True), "name")
			function_info = bn.debuginfo.DebugFunctionInfo(0xadd6355, "short_name", "full_name", "raw_name", bn.types.Type.function(bn.types.Type.int(4, False), None), components=["some", "namespaces"])
			debug_info.add_function(function_info)
		bn.debuginfo.DebugInfoParser.register("debug info parser", is_valid, parse_info)
	:py:class:`DebugInfo` will then be automatically applied to binary views that contain debug information (via the setting `analysis.debugInfo.internal`), binary views that provide valid external debug info files (`analysis.debugInfo.external`), or manually fetched/applied as below::
		valid_parsers = bn.debuginfo.DebugInfoParser.get_parsers_for_view(bv)
		parser = valid_parsers[0]
		debug_info = parser.parse_debug_info(bv, bv)  # See docs for why BV is here twice
		bv.apply_debug_info(debug_info)
	Multiple debug-info parsers can manually contribute debug info for a binary view by simply calling ``parse_debug_info`` with the
	``DebugInfo`` object just returned. This is automatic when opening a binary view with multiple valid debug info parsers. If you
	wish to set the debug info for a binary view without applying it as well, you can call ``'binaryview.BinaryView'.set_debug_info``.

		Some debug file formats need both the original :py:class:`binaryview.BinaryView` (the binary being analyzed/having debug information applied to it) in addition to the :py:class:`binaryview.BinaryView` of the file containing the debug information.
		For formats where you can get all the information you need from a single file, calls to ``parse_debug_info`` are required to provide that file for both arguments.
		For formats where you can get all the information you need from a single file, implementations of `parse` should only read from the second `debug_file` parameter and ignore the former.

class DebugInfo(object):
	``class DebugInfo`` provides an interface to both provide and query debug info. The DebugInfo object is used
	internally by the binary view to which it is applied to determine the attributes of functions, types, and variables
	that would otherwise be costly to deduce.
	DebugInfo objects themselves are independent of binary views; their data can be sourced from any arbitrary binary
	views and be applied to any other arbitrary binary view. A DebugInfo object can also contain debug info from multiple
	DebugInfoParsers. This makes it possible to gather debug info that may be distributed across several different
	formats and files.
	DebugInfo cannot be instantiated by the user, instead you must get it from either the binary view (see ``'binaryview.BinaryView'.debug_info``)
	or a debug-info parser (see ``debuginfo.DebugInfoParser.parse_debug_info``).
	.. note:: Please note that calling one of ``add_*`` functions will not work outside of a debuginfo plugin.
