I would like to use:

writeChunks :: (MonadIO m, Storable a) => Handle -> Fold m (Array a) ()

but have it more modular, that is, move the handle opening and closing 'inside' the fold. In order to do that I need something like bracketIO, but for Folds. It doesn't seem to be currently available in Streamly. Is there a way to bypass this easily, or do I have to write my own bracketIO?

Take a look at this version of writeChunks . It does something similar to what you want.

What the above mentioned writeChunks is doing can be converted into a general Fold bracket combinator I guess.

Thank you @harendra-kumar.

Let's keep this open until it is implemented.
