public class Attribute extends Record
The `PangoAttribute` structure represents the common portions of all
attributes.

Particular types of attributes include this structure as their initial
portion. The common portion of the attribute holds the range to which
the value in the type-specific part of the attribute applies and should
be initialized using [method@Pango.Attribute.init]. By default, an attribute
will have an all-inclusive range of [0,%G_MAXUINT].

    • equal

      public boolean equal(@Nonnull Attribute attr2)
