Wrappers.Coveragetype t = [ `coverage | `object_ ] Gobject.objval new_ : unit -> tCreate a new Coverage
val unref : t -> unitDecrease the reference count on the `PangoCoverage` by one.
If the result is zero, free the coverage and all associated memory.
val set : t -> int -> Pango_enums.coveragelevel -> unitModify a particular index within @coverage
Set the coverage for each index in @coverage to be the max (better) value of the current coverage for the index and the coverage for the corresponding index in @other.
val get : t -> int -> Pango_enums.coveragelevelDetermine whether a particular index is covered by @coverage.
