Variant of Stream::collect() that returns the stream

[srwalter]

Suppose I use collect() in conjunction with take_while():

my_stream.take_while(foo).collect()

In the absence of collect(), I would be able to use TakeWhile::into_inner() to recover the original stream and process the remainder of its data. However, collect() takes ownership of the stream, and there is no way to recover it.

I could envision either implementing Collect::into_inner() or making a variant of collect() whose Item is (Vec<...>, S)

If I'm not mistaken, you can use Stream::by_ref to keep ownership of the underlying stream.
