Expand description

The AttrType distinguishes between different types of attributes. Along with the predefined values, it is possible to allocate additional values for custom attributes using pango_attr_type_register(). The predefined values are given below. The type of structure used to store the attribute is listed in parentheses after the description.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
