Struct Pack 

pub struct Pack<W: Widget> {
    pub inner: W,
    pub hints: AlignHints,
    /* private fields */
}

Apply an alignment hint, squash and align the result

The inner widget chooses how to apply (or ignore) this hint. The widget is then prevented from stretching beyond its ideal size, aligning within the available rect.

Usually, this type will be constructed through one of the methods on AdaptWidget.

Fields

inner: W

hints: AlignHints

Hints may be modified directly.

Use Action::RESIZE to apply changes.
