The alignment field is actually a "pointer sized" type instead of always i64,
requiring that the size of the padding field is also calculated slightly
differently.
Closes#23425
This function is the current replacement for `std::old_io::timer` which will
soon be deprecated. This function is unstable and has its own feature gate as it
does not yet have an RFC nor has it existed for very long.
These two borrowing examples were confusing/misleading. This changes it
to more clearly show how you _can_ borrow a box, and also uses & instead
of &*.

Very minor fix: in `std::net::Ipv6Addr::new`, the documentation had an incomplete representation of the resulting address, missing the last two groups.
This upcast coercion currently never requires vtable changes. It should be generalized.
This is a [breaking-change] -- if you have an impl on an object type like `impl SomeTrait`, then this will no longer be applicable to object types like `SomeTrait+Send`. In the standard library, this primarily affected `Any`, and this PR adds impls for `Any+Send` as to keep the API the same in practice. An alternate workaround is to use UFCS form or standalone fns. For more details, see <https://github.com/rust-lang/rust/issues/18737#issuecomment-78450798>.

This upcast coercion currently preserves the vtable for the object, but
eventually it can be used to create a derived vtable. The upcast
coercion is not introduced into method dispatch; see comment on #18737
for information about why. Fixes#18737.
This looks like the most logical target to give to this link, or at least what I would expect as someone that want to integrate with a native library.

The [associated RFC][rfc] for possibly splitting out `flush` has been closed and
as a result there are no more blockers for stabilizing this method, so this
commit marks the method as such.

To the correct MAP_NORESERVE. Every other instance is known as MAP_NORESERVE, so this is just a basic typo.
I really doubt this will break anybody's but my own code.

This removes the error case of the compression functions, the only errors that
can occur are incorrect parameters or an out-of-memory condition, both of which
are handled with panics in Rust.
Also introduces an extensible `Error` type instead of returning an `Option`.
The type implements a destructor so you can't destructure it.
The RUST_TARGET_STAGE_N rule uses LLVM_LIBDIR_RUSTFLAGS_<target-triple>,
which expands to -L "$(llvm-config --libdir)" when the target-triple is
also a host-triple. Rather than expand to -L "" if llvm-config has not yet
been built, add a dependency on the target llvm-config.
When the target-triple is not a host-triple, the new LLVM_CONFIG_$(2)
dependency should expand to nothing.

- Allow inherent implementations on `char`, `str`, `[T]`, `*const T`, `*mut T` and all the numeric primitives.
- copy `unicode::char::CharExt` methods into `impl char`
- remove `unicode::char::CharExt`, its re-export `std::char::CharExt` and `CharExt` from the prelude
- copy `collections::str::StrExt` methods into `impl str`
- remove `collections::str::StrExt` its re-export `std::str::StrExt`, and `StrExt` from the prelude
- copy `collections::slice::SliceExt` methods into `impl<T> [T]`
- remove `collections::slice::SliceExt` its re-export `std::slice::SliceExt`, and `SliceExt` from the prelude
- copy `core::ptr::PtrExt` methods into `impl<T> *const T`
- remove `core::ptr::PtrExt` its re-export `std::ptr::PtrExt`, and `PtrExt` from the prelude
- copy `core::ptr::PtrExt` and `core::ptr::MutPtrExt` methods into `impl<T> *mut T`
- remove `core::ptr::MutPtrExt` its re-export `std::ptr::MutPtrExt`, and `MutPtrExt` from the prelude
- copy `core::num::Int` and `core::num::SignedInt` methods into `impl i{8,16,32,64,size}`
- copy `core::num::Int` and `core::num::UnsignedInt` methods into `impl u{8,16,32,64,size}`
- remove `core::num::UnsignedInt` and its re-export `std::num::UnsignedInt`
- move `collections` tests into its own crate: `collectionstest`
- copy `core::num::Float` methods into `impl f{32,64}`
Because this PR removes several traits, this is a [breaking-change], however functionality remains unchanged and breakage due to unresolved imports should be minimal. If you encounter an error due to an unresolved import, simply remove the import:
``` diff
fn main() {
- use std::num::UnsignedInt; //~ error: unresolved import `std::num::UnsignedInt`.
-
println!("{}", 8_usize.is_power_of_two());
}
```

This commit performs a stabilization pass over the std::net module,
incorporating the changes from RFC 923. Specifically, the following actions were
taken:
Stable functionality:
* `net` (the name)
* `Shutdown`
* `Shutdown::{Read, Write, Both}`
* `lookup_host`
* `LookupHost`
* `SocketAddr`
* `SocketAddr::{V4, V6}`
* `SocketAddr::port`
* `SocketAddrV4`
* `SocketAddrV4::{new, ip, port}`
* `SocketAddrV6`
* `SocketAddrV4::{new, ip, port, flowinfo, scope_id}`
* Common trait impls for socket addr structures
* `ToSocketAddrs`
* `ToSocketAddrs::Iter`
* `ToSocketAddrs::to_socket_addrs`
* `ToSocketAddrs for {SocketAddr*, (Ipv*Addr, u16), str, (str, u16)}`
* `Ipv4Addr`
* `Ipv4Addr::{new, octets, to_ipv6_compatible, to_ipv6_mapped}`
* `Ipv6Addr`
* `Ipv6Addr::{new, segments, to_ipv4}`
* `TcpStream`
* `TcpStream::connect`
* `TcpStream::{peer_addr, local_addr, shutdown, try_clone}`
* `{Read,Write} for {TcpStream, &TcpStream}`
* `TcpListener`
* `TcpListener::bind`
* `TcpListener::{local_addr, try_clone, accept, incoming}`
* `Incoming`
* `UdpSocket`
* `UdpSocket::bind`
* `UdpSocket::{recv_from, send_to, local_addr, try_clone}`
Unstable functionality:
* Extra methods on `Ipv{4,6}Addr` for various methods of inspecting the address
and determining qualities of it.
* Extra methods on `TcpStream` to configure various protocol options.
* Extra methods on `UdpSocket` to configure various protocol options.
Deprecated functionality:
* The `socket_addr` method has been renamed to `local_addr`
This commit is a breaking change due to the restructuring of the `SocketAddr`
type as well as the renaming of the `socket_addr` method. Migration should be
fairly straightforward, however, after accounting for the new level of
abstraction in `SocketAddr` (protocol distinction at the socket address level,
not the IP address).
[breaking-change]
Most of the changes are cleanup facilitated by straight-forward attribute handling.
This is a minor [breaking-change] for users of `quote_stmt!` (returns `Option<P<Stmt>>` now) and some of the public methods in `Parser` (a few `Vec<Attribute>` arguments/returns were removed).
