Vulkan.Utils.RefCounted

Lightweight reference counter that runs a release action when the count hits zero. Useful for keeping a Vulkan object alive across an unknown number of in-flight frames — bump the count when a frame starts using it, drop the count when the frame retires, and the object is destroyed promptly after the last frame finishes.

A RefCounted will perform the specified action when the count reaches 0

Create a counter with a value of 1

valuereleaseRefCounted :: MonadIO m => RefCounted -> m ()

Decrement the value, the action will be run promptly and in this thread if the counter reached 0.

valuetakeRefCounted :: MonadIO m => RefCounted -> m ()

Increment the counter by 1

valueresourceTRefCount :: MonadResource f => RefCounted -> f ()

Hold a reference for the duration of the MonadResource action
