	 *
	 * This function is not required for normal uses of #GSettings but it
	 * may be useful to authors of plugin management systems.
	 *
	 * The directory should contain a file called `gschemas.compiled` as
	 * produced by the [glib-compile-schemas][glib-compile-schemas] tool.
	 *
	 * If @trusted is %TRUE then `gschemas.compiled` is trusted not to be
	 * corrupted. This assumption has a performance advantage, but can result
	 * in crashes or inconsistent behaviour in the case of a corrupted file.
	 * Generally, you should set @trusted to %TRUE for files installed by the
	 * system and to %FALSE for files in the home directory.
	 *
	 * If @parent is non-%NULL then there are two effects.
	 *
	 * First, if g_settings_schema_source_lookup() is called with the
	 * @recursive flag set to %TRUE and the schema can not be found in the
	 * source, the lookup will recurse to the parent.
	 *
	 * Second, any references to other schemas specified within this
	 * source (ie: `child` or `extends`) references may be resolved
	 * from the @parent.
	 *
	 * For this second reason, except in very unusual situations, the
	 * @parent should probably be given as the default schema source, as
	 * returned by g_settings_schema_source_get_default().
	 *

	 *     directory = the filename of a directory
	 *     parent = a #GSettingsSchemaSource, or %NULL
	 *     trusted = %TRUE, if the directory is trusted
	 *
	 * Since: 2.32
