Type Alias RateConfigStream 

type RateConfigStream = Map<Fuse<Receiver<StreamRateLimit>>, fn(StreamRateLimit) -> RateLimitedWriterConfig>;

A stream of RateLimitedWriterConfig used to update a DynamicRateLimitedWriter.

Unfortunately we need to store the result of a StreamExt::map and StreamExt::fuse in DataWriter, which leaves us with this ugly type. We use a type alias to make DataWriter a little nicer.

Aliased Type

struct RateConfigStream { /* private fields */ }
