	<brief_description>
		Data class wrapper for decoded JSON.
	</brief_description>
	<description>
		Returned by [method JSON.parse], [JSONParseResult] contains the decoded JSON or error information if the JSON source wasn't successfully parsed. You can check if the JSON source was successfully parsed with [code]if json_result.error == OK[/code].

		<member name="error" type="int" setter="set_error" getter="get_error" enum="Error">
			The error type if the JSON source was not successfully parsed. See the [enum Error] constants.
		</member>
		<member name="error_line" type="int" setter="set_error_line" getter="get_error_line" default="-1">
			The line number where the error occurred if the JSON source was not successfully parsed.
		</member>
		<member name="error_string" type="String" setter="set_error_string" getter="get_error_string" default="&quot;&quot;">
			The error message if the JSON source was not successfully parsed. See the [enum Error] constants.
		</member>
		<member name="result" type="Variant" setter="set_result" getter="get_result">
			A [Variant] containing the parsed JSON. Use [method @GDScript.typeof] or the [code]is[/code] keyword to check if it is what you expect. For example, if the JSON source starts with curly braces ([code]{}[/code]), a [Dictionary] will be returned. If the JSON source starts with brackets ([code][][/code]), an [Array] will be returned.
			[b]Note:[/b] The JSON specification does not define integer or float types, but only a [i]number[/i] type. Therefore, parsing a JSON text will convert all numerical values to [float] types.
			[b]Note:[/b] JSON objects do not preserve key order like Godot dictionaries, thus, you should not rely on keys being in a certain order if a dictionary is constructed from JSON. In contrast, JSON arrays retain the order of their elements:
			[codeblocks]
			[gdscript]
			var p = JSON.parse('["hello", "world", "!"]')
			if typeof(p.result) == TYPE_ARRAY:
			    print(p.result[0]) # Prints "hello"
			else:
			    push_error("Unexpected results.")
			[/gdscript]
			[csharp]
			JSONParseResult p = JSON.Parse("[\"hello\"], \"world\", \"!\"]");
			if (p.Result is Godot.Collections.Array)
			{
			    GD.Print((p.Result as Godot.Collections.Array)[0]); // Prints "hello"
			}
			else
			{
			    GD.PushError("Unexpected results.");
			}
			[/csharp]
