Documentation
data RefCounted Source #
A RefCounted will perform the specified action when the count reaches 0
newRefCounted :: MonadIO m => IO () -> m RefCounted Source #
Create a counter with a value of 1
releaseRefCounted :: MonadIO m => RefCounted -> m () Source #
Decrement the value, the action will be run promptly and in this thread if the counter reached 0.
takeRefCounted :: MonadIO m => RefCounted -> m () Source #
Increment the counter by 1
resourceTRefCount :: MonadResource f => RefCounted -> f () Source #
Hold a reference for the duration of the MonadResource action
wrapped :: MonadResource m => m (ReleaseKey, a) -> m (RefCounted, a) Source #
