prevent ice when threshold is 0 and enum has no variants
changelog: [`enum_variant_names`]: prevent ice when threshold is 0 and enum has no variants
r? `@y21`
Fixes the same ice issue raised during review of https://github.com/rust-lang/rust-clippy/pull/11496
This patch sets the two configuration options for
`undocumented_unsafe_blocks` to `true` by default: these are
`accept-comment-above-statement` and `accept-comment-above-attributes`.
Having these values `false` by default prevents what many users would
consider clean code, e.g. placing the `// SAFETY:` comment above a
single-line functino call, rather than directly next to the argument.
changelog: [`undocumented_unsafe_blocks`]: set
`accept-comment-above-statement` and `accept-comment-above-attributes`
to `true` by default.
fix fp when [`undocumented_unsafe_blocks`] not able to detect comment on globally defined const/static variables

Add config flag for reborrows in explicit_iter_loop
This PR adds a config flag for enforcing explicit into iter lint for reborrowed values. The config flag, `enforce_iter_loop_reborrow`, can be added to clippy.toml files to enable the linting behaviour. By default the reborrow lint is disabled.

for reborrowed values. The config flag, enforce_iter_loop_reborrow, can be
added to clippy.toml files to enable the linting behaviour. By default
the lint is not enabled.
"try this" -> "try"
Current help messages contain a mix of "try", "try this", and one "try this instead". In the spirit of #10631, this PR adopts the first, as it is the most concise.
It also updates the `lint_message_conventions` test to catch cases of "try this".
(Aside: #10120 unfairly contained multiple changes in one PR. I am trying to break that PR up into smaller pieces.)
changelog: Make help messages more concise ("try this" -> "try").
Add `needless_if` lint
first off: Sorry about the large diff. Seems a ton of tests do this (understandably so).
this is basically everything I wanted in #10868, while it doesn't lint *all* unnecessary empty blocks, it lints needless if statements; which are basically the crux of the issue (for me) anyway. I've committed code that includes this far too many times 😅 hopefully clippy can help me out soon
closes#10868
changelog: New lint [`needless_if`]
