RectangleRef

public struct RectangleRef : RectangleProtocol

The PangoRectangle structure represents a rectangle.

PangoRectangle is frequently used to represent the logical or ink extents of a single glyph or section of text. (See, for instance, [methodPango.Font.get_glyph_extents].)

The RectangleRef type acts as a lightweight Swift reference to an underlying PangoRectangle instance. It exposes methods that can operate on this data type through RectangleProtocol conformance. Use RectangleRef only as an unowned reference to an existing PangoRectangle instance.

  • ptr 
    Untyped pointer to the underlying `PangoRectangle` instance.

    For type-safe access, use the generated, typed pointer _ptr property instead.
