Gst.Structure.prototype.get_string

function get_string(fieldname:String):String {
    // Gjs wrapper for gst_structure_get_string()
}

Finds the field corresponding to fieldname, and returns the string contained in the field's value. Caller is responsible for making sure the field exists and has the correct type.

The string should not be modified, and remains valid until the next call to a gst_structure_*() function with the given structure.
