…s-zed Disable rust-analyzer diagnostics for Zed

Shimmed TCP sockets are now always backed by a host socket. Before `connect` or `listen` is invoked on the shimmed socket, we just have a `socket2::Socket`. This is socket is then coverted to a `mio::TcpStream` or `mio::TcpListener` after encountering a `connect` or `listen`, respectively. Furthermore, a socket can always be viewed as a `socket2::SockRef`. This allows us to support more socket options than mio provides on its TCP socket abstractions.

Extend TCP socket shim to use `socket2` abstractions

Automatic Rustup

When running on a native host, the `connect` might succeed immediately which would cause some of the non-blocking socket tests to fail. This assertion was only needed to ensure that the `connect` did not fail for any real reason. Thus, the assertion has been adjusted to not fail when the `connect` succeeds immediately.

This updates the rust-version file to 2269776.

These commits modify the Cargo.lock file. Unintentional changes to Cargo.lock can be introduced when switching branches and rebasing PRs.

If this was unintentional then you should revert the changes before this PR is merged.
Otherwise, you can ignore this comment.

miri is developed in its own repository. If the Miri part of this change can be broken out, consider making this change to rust-lang/miri instead. However, if Miri needs adjusting for rustc changes, just ignore this message.

What is this?

This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing 6006fd0 (parent) -> 012c0bd (this PR)

Test differences

Show 2 test diffs

2 doctest diffs were found. These are ignored, as they are noisy.

Test dashboard

Run

cargo run --manifest-path src/ci/citool/Cargo.toml -- \
    test-dashboard 012c0bd4d516934012c9a1ecb26e9eb283d2ed75 --output-dir test-dashboard

And then open test-dashboard/index.html in your browser to see an overview of all executed tests.

Job duration changes

dist-x86_64-netbsd: 1h 2m -> 1h 37m (+56.1%)
test-i686-msvc: 1h 44m -> 2h 33m (+47.7%)
dist-x86_64-illumos: 1h 24m -> 2h (+43.3%)
dist-arm-linux-gnueabi: 1h 3m -> 1h 30m (+41.6%)
test-x86_64-gnu-debug: 2h 10m -> 1h 23m (-36.4%)
test-x86_64-gnu-stdlib-semver-check: 16m 43s -> 10m 44s (-35.8%)

test-x86_64-gnu-parallel-frontend: 2h 10m -> 1h 25m (-34.3%)
test-x86_64-gnu-llvm-21-3: 1h 57m -> 1h 18m (-32.8%)

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
