Remove default features. You need to enable required features
explicitly now. As a quick workaround, you may want to use the
new `full` feature which activates all features.
`StreamMuxerBox` is never shared across threads but owned by a single
connection. Restricting it to be `Sync` unnecessarily limits the design
space around the `StreamMuxer` trait and its implementations.
Instead of having a mix of `poll_event`, `poll_outbound` and `poll_close`, we
flatten the entire interface of `StreamMuxer` into 4 individual functions:
- `poll_inbound`
- `poll_outbound`
- `poll_address_change`
- `poll_close`
This design is closer to the design of other async traits like `AsyncRead` and
`AsyncWrite`. It also allows us to delete the `StreamMuxerEvent`.
Remove the concept of individual `Transport::Listener` streams from `Transport`.
Instead the `Transport` is polled directly via `Transport::poll`. The
`Transport` is now responsible for driving its listeners.
* core/muxing: Remove `Into<io::Error>` bound from `StreamMuxer::Error`
This allows us to preserve the type information of a muxer's concrete
error as long as possible. For `StreamMuxerBox`, we leverage `io::Error`'s
capability of wrapping any error that implements `Into<Box<dyn Error>>`.
* Use `?` in `Connection::poll`
* Use `?` in `muxing::boxed::Wrap`
* Use `futures::ready!` in `muxing::boxed::Wrap`
* Fill PR number into changelog
* Put `Error + Send + Sync` bounds directly on `StreamMuxer::Error`
* Move `Send + Sync` bounds to higher layers
* Use `map_inbound_stream` helper
* Update changelog to match new implementation
`libp2p-core` provides the `StreamMuxer` abstraction so it can provide
functionality that abstracts over this trait.
We never use the `flush_all` function as part of our abstractions.
No one else is going to use it so we can remove it from the abstraction.
Previously `libp2p-swarm` required a `Transport` to be `Clone`. Methods
on `Transport`, e.g. `Transport::dial` would take ownership, requiring
e.g. a `Clone::clone` before calling `Transport::dial`.
The requirement of `Transport` to be `Clone` is no longer needed in
`libp2p-swarm`. E.g. concurrent dialing can be done without a clone per
dial.
This commit removes the requirement of `Clone` for `Transport` in
`libp2p-swarm`. As a follow-up methods on `Transport` no longer take
ownership, but instead a mutable reference (`&mut self`).
On the one hand this simplifies `libp2p-swarm`, on the other it
simplifies implementations of `Transport`.

According to
https://github.com/rust-lang/project-error-handling/issues/44#issuecomment-858151860,
we should not be printing the inner error AND returning it as source. Libraries
like `anyhow` will traverse the chain of `source` errors and build up a composed
error message. Printing it and returning the same error from `source` results in
duplicate error messages in that case.
A `ProtocolsHandler`, now `ConnectionHandler`, handels a connection, not
a protocol. Thus the name `CONNECTIONHandler` is more appropriate.
Next to the rename of `ProtocolsHandler` this commit renames the `mod
protocols_handler` to `mod handler`. Finally all combinators (e.g.
`ProtocolsHandlerSelect`) are renamed appropriately.
