Proposing to replace
```rust
let mut x = PathBuf::from("/foo");
x.push("/bar");
```
by
```rust
let mut x = PathBuf::from("/foo");
x.push("bar");
```
changes the content of `x` (`/bar` ⇒ `/foo/bar`).
By assuming that a recursive type is normalizable within the deeper calls to `is_normalizable_helper()`, more cases can be handled by this function. In order to fix stack overflows, a recursion limit has also been added for recursive generic type instantiations.
`manual_ok_or` covers the same case that were covered by `option_map_or_err_ok` which is not deprecated. The latter was in the "style" category. Also, the lint is machine applicable, and leads to shorter and more readable code, so "style" is appropriate. The only difference is that the η-expanded form of `Result::Ok()` was not covered by `option_map_or_err_ok` while it is by `manual_ok_or`, so the category change may expose some new occurrences.
Removing the `.as_ref()` or `.as_mut()` as the top-level expression in a closure may change the type of the result. In this case, it may be better not to lint rather than proposing a fix that would not work.
Labeled blocks cannot be used as-is in the "then" or "else" part of an `if` expression. They must be enclosed in an anonymous block.
This is the lint described at rust-lang#136308 (comment) that recommends using HTML to nest links inside code.
- `reindent_multiline()` always returns the result of
`reindent_multiline_inner()` which returns a `String`. Make
`reindent_multiline()` return a `String` as well, instead of a
systematically owned `Cow<'_, str>`.
- There is no reason for `reindent_multiline()` to force a caller to
build a `Cow<'_, str>` instead of passing a `&str` directly,
especially considering that a `String` will always be returned.
Also, both the input parameter and return value (of type `Cow<'_, str>`)
shared the same (elided) lifetime for no reason: this worked only because
the result was always the `Cow::Owned` variant which is compatible with
any lifetime.
As a consequence, the signature changes from:
```rust
fn reindent_multiline(s: Cow<'_, str>, …) -> Cow<'_, str> { … }
```
to
```rust
fn reindent_multiline(s: &str, …) -> String { … }
```
