A matryoshka doll, also known as Russian nesting doll or Russian doll, refers to a set of wooden dolls of decreasing size placed one inside the other. — Wikipedia
Matryoshka is more of an architectural approach and structural help than an actual framework. It is fundamentally build around the idea of creating a SignalProducer that, when started, will execute a task with a given input, then forward the results upon the produced Signal. This can be represented as a function:
Input -> SignalProducer<Output, Error>Very often, a task can be divided into subtasks or transformed into another task, enabling delegation of its actual execution to another function of similar signature. Again, this can be represented as a function:
Input -> (ExecuteInput -> SignalProducer<ExecuteOutput, ExecuteError>) -> SignalProducer<Output, Error>Splitting up the execution of a task into multiple such functions can have several benefits, including greater reusability, composability and testability.
Matryoshka provides a few very basic types and functions that help separating the initialization and execution of such operations. It also provides some handy signal producer operators and transformers that ease chaining and nesting.
Please take a look at the code, it ain't much anyways 😉
There is a playground and an accompanying project that implements a network layer and a few operations of the official SoundCloud API. It's very basic, just have a look 😅
