The text says it's a vector of floats, but the code actually uses a vector of integers. The type of the Vec doesn't really matter, so I just cut it from the text.
Fixes issue #29077.
There **are** API changing guidelines in the RFCs, so it might be prudent to put those there. But I'm leaving that up to another person. This PR just removes bad documentation.
When going through the docs, it is not clear that binary files cannot be tested. Additionally, it is hard to find the proper structure of a Rust crate and it took me several hours of looking through the docs to find the crates and modules section. I think we can link to it from here and it will be beneficial to those who are coming to the language.
The implementation for `into_inner` was a bit more complex than I had hoped for---is there any simpler, less unsafe way of getting around the fact that one can't move out of a `Drop` struct?
See #28968 and rust-lang/rfcs#1269 .

This commit adds `#[derive(Clone)]` to `std::fs::Metadata`, making that struct cloneable. Although the exact contents of that struct differ between OSes, they all have it contain only value types, meaning that the data can be re-used without repercussions.
It also adds `#[derive(Clone)]` to every type used by that struct across all OSes, including the various Unix `stat` structs and Windows's `WIN32_FILE_ATTRIBUTE_DATA`.
This stems from my comment here: https://github.com/rust-lang/rfcs/issues/939#issuecomment-140524439
Regarding [#29063 _[Docs] Terminology inconsistency between 'iterator adapters' and 'iterator adaptors'_](https://github.com/rust-lang/rust/issues/29063) :
This PR replaces 'iterator adapters' appearances (in TRPL book) to 'iterator adaptors', thus embracing the terminology used along the API docs and achieving consistency between both sources.
Before this commit, the first "A Rust library" code sample produced
the following compilation warning:
```
test.rs:7:22: 7:36 warning: unnecessary parentheses around `for` head
expression, #[warn(unused_parens)] on by default
test.rs:7 for _ in (0..5_000_000) {
```
This commit just removes the parens around the range 0..5_000_000 thereby removing the compilation warning.
Fixes#28676.
There doesn't seem to be a good way to add a test for this, but I tested the repro in #28676 and confirmed it now yields the correct result.

This is needed as item types are allowed to be unnormalized.
Fixes an ICE that occurs when foreign function signatures contained
an associated type.
Fixes#28983
