Some keyword documentation. I thought about going into detail, but I'd much rather route them to the async book asap.

2019-12-28Rollup merge of #67635 - Mark-Simulacrum:path-doc-unsafe, r=dtolnayOliver Scherer-0/+7
Document safety of Path casting I would personally feel more comfortable making the relevant (internal anyway) types repr(transparent) and then documenting that we can make these casts because of that, but I believe this is a more minimal PR, so posting it first. Resolves #45910.

2019-12-28Rollup merge of #67629 - kraai:remove-redundant-link-texts, r=steveklabnikOliver Scherer-4/+4
Remove redundant link texts Most of these links are followed by a parenthesized expression. I think that the redundant link texts were added to prevent interpretation as an inline link. This is unnecessary since the closing square bracket and opening parenthesis are separated by whitespace.

add IntoFuture trait and support for await The [async-await RFC](https://rust-lang.github.io/rfcs/2394-async_await.html#the-await-compiler-built-in) mentions being able to `await` anything implementing `IntoFuture`. Somewhere along the way, it was left out.

2019-12-24Deprecate Error::description for realDavid Tolnay-124/+79
`description` has been documented as soft-deprecated since 1.27.0 (17 months ago). There is no longer any reason to call it or implement it. This commit: - adds #[rustc_deprecated(since = "1.41.0")] to Error::description; - moves description (and cause, which is also deprecated) below the source and backtrace methods in the Error trait; - reduces documentation of description and cause to take up much less vertical real estate in rustdocs, while preserving the example that shows how to render errors without needing to call description; - removes the description function of all *currently unstable* Error impls in the standard library; - marks #[allow(deprecated)] the description function of all *stable* Error impls in the standard library; - replaces miscellaneous uses of description in example code and the compiler.

Fix up Command Debug output when arg0 is specified. PR https://github.com/rust-lang/rust/pull/66512 added the ability to set argv[0] on Command. As a side effect, it changed the Debug output to print both the program and argv[0], which in practice results in stuttery output (`"echo" "echo" "foo"`). This PR reverts the behaviour to the the old one, so that the command is only printed once - unless arg0 has been set. In that case it emits `"[command]" "arg0" "arg1" ...`.

2019-12-19Rollup merge of #67270 - alexcrichton:write-more-line-writer, r=sfacklerMazdak Farrokhzad-1/+171
std: Implement `LineWriter::write_vectored` This commit implements the `write_vectored` method of the `LineWriter` type. First discovered in bytecodealliance/wasmtime#629 the `write_vectored` method of `Stdout` bottoms out here but only ends up writing the first buffer due to the default implementation of `write_vectored`. Like `BufWriter`, however, `LineWriter` can have a non-default implementation of `write_vectored` which tries to preserve the vectored-ness as much as possible. Namely we can have a vectored write for everything before the newline and everything after the newline if all the stars align well. Also like `BufWriter`, though, special care is taken to ensure that whenever bytes are written we're sure to signal success since that represents a "commit" of writing bytes.

2019-12-16Rollup merge of #67308 - dtolnay:fast_rebind, r=alexcrichtonMazdak Farrokhzad-15/+0
Delete flaky test net::tcp::tests::fast_rebind This test is unreliable for at least 3 users on two platforms: see #57509 and #51006. It was added 5 years ago in #22015. Do we know whether this is testing something important that would indicate a bug in our implementation, or if it's fine to remove? r? @sfackler @alexcrichton because this somewhat resembles #59018 Closes #57509. Closes #51006.

Require stable/unstable annotations for the constness of all stable fns with a const modifier r? @RalfJung @Centril Every `#[stable]` const fn now needs either a `#[rustc_const_unstable]` attribute or a `#[rustc_const_stable]` attribute. You can't silently stabilize the constness of a function anymore.
2019-12-14Auto merge of #67084 - Pagten:feature/print-msg-from-elf-entrypoint, r=Amanieubors-0/+30
SGX: Change ELF entrypoint This fixes [rust-sgx issue #148](https://github.com/fortanix/rust-sgx/issues/148). A new entry point is created for the ELF file generated by `rustc`, separate from the enclave entry point. When the ELF file is executed as a Linux binary, the error message below is written to stderr. > Error: This file is an SGX enclave which cannot be executed as a standard Linux binary. > See the installation guide at https://edp.fortanix.com/docs/installation/guide/ on how to use 'cargo run' or follow the steps at https://edp.fortanix.com/docs/tasks/deployment/ for manual deployment. When the ELF file is converted to an SGXS using `elf2sgxs`, the old entry point is still set as the enclave entry point. In a future pull request in the rust-sgx repository, `elf2sgxs` will be modified to remove the code in the ELF entry point, since this code is not needed in the enclave.
