Until `if let` chains are stabilized, we do not collapse them together
or with other `if` expressions unless the `let_chains` feature is
enabled. This is the case for example in Clippy sources.
This was made possible by converting the `collapsible_if` to a late lint
to get access to the set of enabled features. This allows this PR to
supersede #14455 and no longer require an additional configuration
option.
The three commits are, in order:
- a conversion of the existing early lint to a late lint, with no new
feature or tests changes
- the addition of the `let_chains` feature detection and action, and
tests
- the application of the enhanced lint to Clippy sources (136 files
modified)
changelog: [`collapsible_if`]: recognize the rust compiler `let_chains`
feature
r? @flip1995
Until `if let` chains are stabilized, we do not collapse them together
or with other `if` expressions unless the `let_chains` feature is
enabled. This is the case for example in Clippy sources.
This extra condition prevents a problem when removing the '}' in:
```rust
( // There was an opening bracket after the parenthesis, which has been removed
// This is a comment
})
```
Removing the whitespaces, including the linefeed, before the '}', would put the
closing parenthesis at the end of the `// This is a comment` line, which would
make it part of the comment as well. In this case, it is best to keep the span
on the '}' alone.
This lint was downgraded to `pedantic` in part because rust-analyzer was not fully supporting it at the time per #10087. The support has been added over [a year ago](https://github.com/rust-lang/rust-analyzer/issues/11260), so seems like this should be back to style.
Another source of the initial frustration was fixed since then as well - this lint does not trigger by default in case only some arguments can be inlined.
This PR does two things:
- It renames `inconsistent_struct_constructor`'s configuration from
`lint-inconsistent-struct-field-initializers` to
`check-inconsistent-struct-field-initializers`. (I should have suggested
`check-...` in
[#13737](https://github.com/rust-lang/rust-clippy/pull/13737#discussion_r1875118516).)
- It causes Clippy to no longer suggest deprecated configurations.
(Previously, Clippy would suggest `cyclomatic-complexity-threshold`, for
example.)

`warn_on_all_wildcard_imports` should warn on all wildcard imports,

Fix#13660
changelog: [`warn_on_all_wildcard_imports`]: when asked to warn on all
wildcard imports, include the reexported ones
Replace the use of `Sugg::ast()` which prevented combining `if`
together when they contained comments by span manipulation.
A new configuration option `lint_commented_code`, which is `true` by
default, opts out from this behavior.
From feedback to this lint after its inclusion in clippy 1.82, this has
turned out to be the most requested improvement. With this improvement,
it is possible to make the lint check certain top-level structural
checks on modules (e.g. use statements and module inclusions at the top),
but still leaving everything else up to the developer.
By default, do not lint `.unwrap()` and `.expect(…)` in always const
contexts, as a failure would be detected at compile time anyway.
New options `allow_expect_in_consts` and `allow_unwrap_in_consts`,
defaulting to `true`, can be turned unset to still lint in always const
contexts.

Fixes#11846.
This PR has three commits:
- The first commit adds an `initializer-suggestions` configuration to
control suggestion applicability when initializers are present. The
following are the options:
- "none": do not suggest
- "maybe-incorrect": suggest, but do not apply suggestions with `--fix`
- "machine-applicable": suggest and apply suggestions with `--fix`
- The second commit fixes suggestions to handle field attributes
(problem [noticed by
@samueltardieu](https://github.com/rust-lang/rust-clippy/pull/13737#discussion_r1859261645)).
- The third commit adds `initializer-suggestions = "machine-applicable"`
to Clippy's `clippy.toml` and applies the suggestions. (Nothing seems to
break.)

changelog: make `inconsistent_struct_constructor` "all fields are
shorthand" requirement configurable
Consider comments and bare delimiters the same as an "empty line" for purposes of hiding rendered code output of long multispans. This results in more aggressive shortening of rendered output without losing too much context, specially in `*.stderr` tests that have "hidden" comments.
