Motivation

A user defined I/O closure should be called by mio's try_io to ensure that the I/O receives more events if it hits a WouldBlock error.

Solution

Make tokio's try_io methods call mio's try_io method using a given closure.

Fixes: #4510

I strongly suspect that you will need to increase the minimum required version of mio in our Cargo.toml.

I don't know about Tokio internal (registration) state but the calls to try_io should ensure that Mio's state is correctly updated once it hits an Wouldblock error.

I forgot it. I've just added the change.

You need to run rustfmt. See the contributing.md file for info on how to do that.

@Darksonn I've run it.

tokio: prepare to release v1.18.0
6fcaea7 
# 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])
