The minimal requirements of the writable store contract.
A minimal writable is a Readable / subscribable, but only has a
setmethod omitting theupdatemethod fromWritable.Extends the minimal writable interface to allow type differentiation between writing and reading data. This is useful when converting or transforming input data to a different or more specific output.
