7/// Represents a format usable with the clipboard and drag-and-drop, with a
8/// data type.
9///
10/// `T` is the type of the values of the format as they are handed out:
11/// [`String`] for text, `Rc<[u8]>` for bytes, `Rc<Bitmap>` for bitmaps. It
12/// is only used to resolve the typed accessors.
13///
14/// This type cannot be instantiated directly. Use universal formats such as
15/// [`DataFormat::text`], or create custom formats using
16/// [`DataFormat::create_bytes_application_format`],
17/// [`DataFormat::create_string_application_format`],
18/// [`DataFormat::create_bytes_platform_format`],
19/// [`DataFormat::create_string_platform_format`] or
20/// [`DataFormat::create_in_process_format`].
