async_stream_impl 0.3.1 removes stream, try_stream, breaking async_stream =0.3.0

[dfreese]

I had async_stream pinned to "=0.3.0", and as a result, ran into the following error:

error[E0432]: unresolved imports `async_stream_impl::stream`, `async_stream_impl::try_stream`
   --> external/raze__async_stream__0_3_0/src/lib.rs:171:29

error: aborting due to previous error

We try to pin our main dependencies, to keep a little more control over how things update. Updating to 0.3.1 for async stream 0.3.1 isn't a problem, but should 0.3.1 have been 0.4?

async_stream_impl is Implementation detail of the async_stream crate. It is not intended to depend directly and most crates do not support updating only implementation details.

However, this issue has been fixed in 0.3.1 (#52 (comment)) and should not occur in future versions.

I recommend using Cargo.lock for this purpose. Doing this using Cargo.toml is not intended and usually does not work.
