CoverageRef

public struct CoverageRef : CoverageProtocol, GWeakCapturing

A PangoCoverage structure is a map from Unicode characters to [enumPango.CoverageLevel] values.

It is often necessary in Pango to determine if a particular font can represent a particular character, and also how well it can represent that character. The PangoCoverage is a data structure that is used to represent that information. It is an opaque structure with no public fields.

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

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

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