```rust
fn foo() {
let mut arr = [1i32];
$0arr[0] = 3;$0
let _ = arr;
}
```
**Before this PR**
```rust
fn foo() {
let mut arr = [1i32];
fun_name(&mut arr);
let _ = arr;
}
fn $0fun_name(arr: &mut [i32; 1]) {
*arr[0] = 3;
}
```
**After this PR**
```rust
fn foo() {
let mut arr = [1i32];
fun_name(&mut arr);
let _ = arr;
}
fn $0fun_name(arr: &mut [i32; 1]) {
arr[0] = 3;
}

I chose the order of mut restrictions to be `unsafe mut(...)` for unsafe fields, but it's undecided yet.

internal: Fix rustdoc quoting
Previously, we didn't recurse in Evaluator::create_memory_map() or Evaluator::patch_addresses() when handling references with a known size. This caused problems for hover rendering on const values, which would build a memory map for evaluated allocations and then pretty-printed values by following references through that map. As a result, references in the map still pointed to the original addresses, meaning that the value pretty-printer would see the type parameters before substitution. This could cause stack overflows on well-formed Rust code using recursive const functions. Add a regression test for hovering on a recursive const fn that previously caused stack overflow. Fixes rust-lang/rust-analyzer#21503 AI disclosure: I used Codex with GPT 5.4 to investigate the issue and write the initial version of this commit.
We want to complain on PRs that generate rustdoc warnings, but only deploy the generate HTML on the master branch. Also fix the existing rustdoc warning. AI disclosure: Some Claude Opus usage.
internal: Ensure rustdoc GitHub action runs on PRs
Fixes rust-lang/rust-analyzer#21891. Previously, the completion engine would aggressively bail out if the parent enum was marked . This pushes the visibility check down to the individual variants so they can be properly completed when accessed via a public type alias.
…ocal_inherent_impl_on_render Demoting completion relevance when an inherent impl already exists
fix: MIR evaluation of sized &T with recursive const fn
fix: complete variants of hidden enums through public aliases
fix: enable vscode suggest in strings
Update generated lints
This is a quick fix, please review if there is a regression

**After this PR**
