net: add peer_addr to UdpSocket #4611

Conversation

Contributor

@PoorlyDefinedBehaviour PoorlyDefinedBehaviour commented Apr 9, 2022

Motivation

The std UdpSocket exposes the method peer_addr to get the address of the remote peer the socket is connected to but tokio UdpSocket does not.

There are other ways to get the peer address as mentioned in #4609 but peer_addr makes it convenient.

Fixes: #4609

Solution

Implement peer_addr for UdpSocket and forward the call to mio.

The std UdpSocket has the peer_addr method which can be used to get the address of the remote peer the socket is connected to.

Fixes: tokio-rs#4609

# 1.18.0 (April 27, 2022)

This release adds a number of new APIs in `tokio::net`, `tokio::signal`, and
`tokio::sync`. In addition, it adds new unstable APIs to `tokio::task` (`Id`s
for uniquely identifying a task, and `AbortHandle` for remotely cancelling a
task), as well as a number of bugfixes.

### Fixed

- blocking: add missing `#[track_caller]` for `spawn_blocking` ([#4616])
- macros: fix `select` macro to process 64 branches ([#4519])
- net: fix `try_io` methods not calling Mio's `try_io` internally ([#4582])
- runtime: recover when OS fails to spawn a new thread ([#4485])

### Added

- macros: support setting a custom crate name for `#[tokio::main]` and
  `#[tokio::test]` ([#4613])
- net: add `UdpSocket::peer_addr` ([#4611])
- net: add `try_read_buf` method for named pipes ([#4626])
- signal: add `SignalKind` `Hash`/`Eq` impls and `c_int` conversion ([#4540])
- signal: add support for signals up to `SIGRTMAX` ([#4555])
- sync: add `watch::Sender::send_modify` method ([#4310])
- sync: add `broadcast::Receiver::len` method ([#4542])
- sync: add `watch::Receiver::same_channel` method ([#4581])
- sync: implement `Clone` for `RecvError` types ([#4560])

### Changed

- update `nix` to 0.24, limit features ([#4631])
- update `mio` to 0.8.1 ([#4582])
- macros: rename `tokio::select!`'s internal `util` module ([#4543])
- runtime: use `Vec::with_capacity` when building runtime ([#4553])

### Documented

- improve docs for `tokio_unstable` ([#4524])
- runtime: include more documentation for thread_pool/worker ([#4511])
- runtime: update `Handle::current`'s docs to mention `EnterGuard` ([#4567])
- time: clarify platform specific timer resolution ([#4474])
- signal: document that `Signal::recv` is cancel-safe ([#4634])
- sync: `UnboundedReceiver` close docs ([#4548])

### Unstable

The following changes only apply when building with `--cfg tokio_unstable`:

- task: add `task::Id` type ([#4630])
- task: add `AbortHandle` type for cancelling tasks in a `JoinSet` ([#4530],
  [#4640])
- task: fix missing `doc(cfg(...))` attributes for `JoinSet` ([#4531])
- task: fix broken link in `AbortHandle` RustDoc ([#4545])
- metrics: add initial IO driver metrics ([#4507])
