Since it doesn't utilize the parameter, it's not very idiomatic since it
could just use the `Result::or` method. So this changes the example to
utilize the parameter. As far as I can tell, all the numbers in this
example are completely arbitrary.
This is a little bit tricky, since with include_str!, we know that we
are including utf-8 content, so it's safe to store the source as a
String in a FileMap. We don't know that for include_bytes!, but I don't
think we actually need to track the contents anyways, so I'm passing "".
new_filemap does check for the zero length content, and it should be
reasonable, howeven I'm not sure if it would be better to pass None
instead of Some(Rc::new("")) as the src component of a FileMap.
Fixes bug #24348
As pointed out in [RFC issue 1043][rfc] it is quite useful to have the standard
I/O types to provide the contract that they are the sole owner of the underlying
object they represent. This guarantee enables writing safe interfaces like the
`MemoryMap` API sketched out in that issue.
[rfc]: https://github.com/rust-lang/rfcs/issues/1043
As constructing objects from these raw handles may end up violating these
ownership gurantees, the functions for construction are now marked unsafe.

Feel silly because it's just one thing but it was bothering me that the documentation tells you what you're not going to learn now instead of linking to the item in question. Am total noob pls assist, where is power button. :)
`thread::spawn` was previously restricted to closures that return `()`,
which limited the utility of joining on a spawned thread. However, there
is no reason for this restriction, and this commit allows arbitrary
return types.
Since it introduces a type parameter to `JoinHandle`, it's technically
a:

However, no code is actually expected to break.
- Adds two more functions for broadcast address and special
address classes reserved for documentation
- Modifies the globally routable IP check to include these
new functions
Fixes#24314
Issue #24292 demonstrates that the `scoped` API as currently offered can
be memory-unsafe: the `JoinGuard` can be moved into a context that will
fail to execute destructors prior to the stack frame being popped (for
example, by creating an `Rc` cycle).
This commit reverts the APIs to `unstable` status while a long-term
solution is worked out.
(There are several possible ways to address this issue; it's not a
fundamental problem with the `scoped` idea, but rather an indication
that Rust doesn't currently provide a good way to ensure that
destructors are run within a particular stack frame.)
[breaking-change]
The current implementation of using GetFinalPathNameByHandle actually reads all
intermediate links instead of just looking at the current link. This commit
alters the behavior of the function to use a different API which correctly reads
only one level of the soft link.
