## Motivation Often developers want to pipe the contents of an async reader into a writer. This is a common scenario in asynchronous streaming APIs. Readers are modeling sources of data where writers are modeling sinks. As an example imagine reading from a network socket and writing the contents into a file. Importantly, the entire operation needs to uphold backpressure. ## Modifications This PR adds 2 new `pipe` methods to each reader one for each writer type. Depending on the buffer ownership those methods will the pipe operation is copy free, requires a copy or even requires an intermediate allocation for copying. The method parameter labels are trying to express what the operation does. ## Result It is very easy for developers now to move elements from readers into writers.
