`delay_span_bug` when codegen cannot select obligation
Fix#69602, introduced in #60126 by letting the compiler continue past
type checking after encountering errors.
even more clippy cleanups
* Don't pass &mut where immutable reference (&) is sufficient (clippy::unnecessary_mut_passed)
* Use more efficient &&str to String conversion (clippy::inefficient_to_string)
* Don't always eval arguments inside .expect(), use unwrap_or_else and closure. (clippy::expect_fun_call)
* Use righthand '&' instead of lefthand "ref". (clippy::toplevel_ref_arg)
* Use simple 'for i in x' loops instead of 'while let Some(i) = x.next()' loops on iterators. (clippy::while_let_on_iterator)
* Const items have by default a static lifetime, there's no need to annotate it. (clippy::redundant_static_lifetimes)
* Remove redundant patterns when matching ( x @ _ to x) (clippy::redundant_pattern)
more clippy cleanups
* Don't use .ok() before unwrapping via .expect() on a Result.
* Use .map() to modify data inside Options instead of using .and_then(|x| Some(y))
* Use .as_deref() instead of .as_ref().map(Deref::deref)
* Don't use "if let" bindings to only check a value and not actually bind anything.
* Use single-char patter on {ends,starts}_with and remove clone on copy type.
const limit for CTFE
I tried to tackle the first steps for this issue.
The active feature flag does link to the issue below, I think this has to change, because there should be a tracking issue?
1679a7647d/src/librustc_feature/active.rs (L530)
Also, I only put up the storage of the limit like "recursion_limit" but created a seperate file in the same place. Since I guess the invocation happens seperately.
https://github.com/TheSamsa/rust/blob/const-limit/src/librustc/middle/const_limit.rs
If this does not hold up for the issue and since there is a time pressure, just reject it.
hopefully this does not put more load on you than I expected...
submodules: update clippy from 8b7f7e66 to 74eae9dc
Changes:
````
Rustup to rust-lang/rust#69506
Revive rls integration test
use question mark operator
Add regression test
Use `try_eval_usize` over `eval_usize`
Add path for display trait
Use lang items instead of get_trait_def_id where possible
Update stderr
Don't lint debug formatting in debug impl
Whitelist unused attribute for use items.
add test for #5238
````
Makes clippy tests pass again.
r? @oli-obk
Correctly reject `TraitCandidate` in all cases
Follow up to #69255, addresses #69629.
When `self.select_trait_candidate(trait_ref)` returned `Err(_)`, `result` wasn't being set to `NoMatch`, causing invalid methods to be selected.
