GI.Gst.Objects.TracerRecord
Contents
Description
Tracing modules will create instances of this class to announce the data they will log and create a log formatter.
Synopsis
- newtype TracerRecord = TracerRecord (ManagedPtr TracerRecord)
- class GObject o => IsTracerRecord o
- toTracerRecord :: (MonadIO m, IsTracerRecord o) => o -> m TracerRecord
- noTracerRecord :: Maybe TracerRecord
Exported types

toTracerRecord :: (MonadIO m, IsTracerRecord o) => o -> m TracerRecord Source #
Cast to TracerRecord, for types for which this is known to be safe. For general casts, use castTo.
noTracerRecord :: Maybe TracerRecord Source #
A convenience alias for Nothing :: Maybe TracerRecord.
