🔹 What is an Accumulator? In Play, an Accumulator represents a streaming computation that consumes incoming request body chunks and eventually produces a result. Its type is: Accumulator[E, A] E: the type of incoming chunks (often ByteString) A: the final result once the stream completes (often a Result) Think of it as a pipe: It gathers chunks of request data → processes them asynchronously → produces a final response.
