* tutorial/receiving_messages: fix future output type bound
* tutorial/receiving_messages: remove unneeded message trimming
Trimming was done twice on messages, so one of the two instances can
be removed. I personally think removing the first instance, in which
we are splitting names from messages makes the code more readable
than removing the second instance, but other examples further in
the tutorial show the second instance removed.
* tutorial/receiving_messages: declare use of TcpStream and io::BufReader
Readers couldn't see the `use` lines corresponding to these two
structures.
* tutorial/connecting_readers_and_writers: typos and grammar fixes
* tutorial/all_together: remove unneeded use async_std::io
* tutorial: use SinkExt consistently from futures::sink::SinkExt
* tutorial/handling_disconnection: hide mpsc use clause and remove empty lines
The empty lines translate to the output making it look weird.
* tutorial/handling_disconnection: fix typos
* tutorial/handling_disconnection: use ? in broker_handle.await
We were happy to return an Err variant from the broker_handle before
and nothing has changed in this regard, so bubbling it up to run().
224: Re-export IO traits from futures r=stjepang a=stjepang
Sorry for the big PR!
Instead of providing our own traits `async_std::io::{Read, Write, Seek, BufRead}`, we now re-export `futures::io::{AsyncRead, AsyncWrite, AsyncSeek, AsyncRead}`. While re-exporting we rename them to strip away the "Async" prefix.
The documentation will display the contents of the original traits from the `futures` crate together with our own extension methods. There's a note in the docs saying the extenion methods become available only when `async_std::prelude::*` is imported.
Our extension traits are re-exported into the prelude, but are marked with `#[doc(hidden)]` so they're completely invisible to users.
The benefit of this is that people can now implement traits from `async_std::io` for their types and stay compatible with `futures`. This will also simplify some trait bounds in our APIs - for example, things like `where Self: futures_io::AsyncRead`.
At the same time, I cleaned up some trait bounds in our stream interfaces, but haven't otherwise fiddled with them much.
I intend to follow up with another PR doing the same change for `Stream` so that we re-export the stream trait from `futures`.
