 The answer is that in the C++ version, `x` is a *reference* to the memory
 location where the first element of the array is stored. But in Ruby, `x` is a

 the details for a moment. Your program has access to memory, provided to it by
 the operating system. Each location in memory has an address.  So when we make
 our vector, `v`, it's stored in a memory location somewhere:

Subject: [PATCH 05/54] Remove `_VALUE` from the float extremes constants.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In `std::f32` and `std::f64`:

- `MIN_VALUE` → `MIN`
- `MAX_VALUE` → `MAX`
- `MIN_POS_VALUE` → `MIN_POSITIVE`

This matches the corresponding integer constants.

Rollup merge (373cbab5b08d6630da58f28d2166c19afc327fa6) of PR #20723
accidentally reverted a portion of commit
8327bcc167661c26ca5c6b967309ff745d302329 which shifted

+## Diverging functions
+
+Rust has some special syntax for 'diverging functions', which are functions that
+do not return:
+
+```
+fn diverges() -> ! {
+    panic!("This function never returns!");
+}
+```
+
+`panic!` is a macro, similar to `println!()` that we've already seen. Unlike
+`println!()`, `panic!()` causes the current thread of execution to crash with
+the given message.
+
+Because this function will cause a crash, it will never return, and so it has
+the type '`!`', which is read "diverges." A diverging function can be used
+as any type:
+
+```should_fail
+# fn diverges() -> ! {
+#    panic!("This function never returns!");
+# }
+
+let x: i32 = diverges();
+let x: String = diverges();
+```
+
+We don't have a good use for diverging functions yet, because they're used in
+conjunction with other Rust features. But when you see `-> !` later, you'll
+know what it's called.

 together, and you are just testing the type checker, not the runtime
 semantics.

 If you remember, the `::<>` syntax allows us to give a type hint,

 `collect()` is the most common consumer, but there are others too. `find()`

Subject: [PATCH 31/54] Remove ExactSizeIterator from 64-bit ranges.

Fixes #22047

Range and Range may be longer than usize::MAX on 32-bit
platforms, and thus they cannot fulfill the protocol for
ExactSizeIterator. We don't want a nonobvious platform dependency in
basic iterator traits, so the trait impl is removed.

The logic of this change assumes that usize is at least 32-bit.

This is technically a breaking change; note that Range and
Range are always ExactSizeIterators.

Subject: [PATCH 33/54] Forbid `pub mymacro!();`

It's not clear what this means, because a macro in item position can expand to
zero or more items.  For now we disallow it, which is technically a

    [breaking-change]

but is landing without an RFC.  The `pub` keyword previously had no effect,
which seems quite unintended.

Fixes #18317.
Fixes #14660.

Subject: [PATCH 39/54] Dramatically expand the docs of std::raw.

This overhauls the very meager docs that currently exist to clarify
various understandable confusions that I've noticed, e.g. people look in
`std::raw` for the "real" types of slices like `&[T]`, or think that
`Slice` refers to `[T]` (fixes #22214).

This patch takes the liberty of offering some "style" guidance around
`raw::Slice`, since there's more restricted ways to duplicate all
functionality connected to it: `std::slice::from_raw_parts{,_mut}` for
construction and `.as_{,mut_}ptr` & `.len` for deconstruction.

It also deprecates the `std::raw::Closure` type which is now useless for
non-type-erased closures, and replaced by `TraitObject` for `&Fn`, `&mut
FnMut` etc, so I guess it should be called a:

The default implementation of .repr() will call conveniently call
transmute_copy which should be appropriate for all implementors, but is
memory unsafe if used wrong.

Fixes #22260

You need to use `unsafe impl` to implement the Repr trait now.

`PathBuf` does implement `Hash`, but `Path` doesn't. This makes it
annoying if you have a `HashMap` with `PathBuf`s as keys, because
it means you have to convert a `Path` into a `PathBuf` and get a
reference to it simply to perform operations on the `HashMap`!
