Version 1.42.0 (2020-03-12)
==========================
Language
--------
- [You can now use the slice pattern syntax with subslices.][67712] e.g.
```rust
fn foo(words: &[&str]) {
match words {
["Hello", "World", "!", ..] => println!("Hello World!"),
["Foo", "Bar", ..] => println!("Baz"),
rest => println!("{:?}", rest),
}
}
```
- [You can now use `#[repr(transparent)]` on univariant `enum`s.][68122] Meaning
that you can create an enum that has the exact layout and ABI of the type
it contains.
- [There are some *syntax-only* changes:][67131]
- `default` is syntactically allowed before items in `trait` definitions.
- Items in `impl`s (i.e. `const`s, `type`s, and `fn`s) may syntactically
leave out their bodies in favor of `;`.
- Bounds on associated types in `impl`s are now syntactically allowed
(e.g. `type Foo: Ord;`).
- `...` (the C-variadic type) may occur syntactically directly as the type of
any function parameter.
These are still rejected *semantically*, so you will likely receive an error
but these changes can be seen and parsed by procedural macros and
conditional compilation.
Compiler
--------
- [Added tier 2\* support for `armv7a-none-eabi`.][68253]
- [Added tier 2 support for `riscv64gc-unknown-linux-gnu`.][68339]
- [`Option::{expect,unwrap}` and
`Result::{expect, expect_err, unwrap, unwrap_err}` now produce panic messages
pointing to the location where they were called, rather than
`core`'s internals. ][67887]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`iter::Empty<T>` now implements `Send` and `Sync` for any `T`.][68348]
- [`Pin::{map_unchecked, map_unchecked_mut}` no longer require the return type
to implement `Sized`.][67935]
- [`io::Cursor` now derives `PartialEq` and `Eq`.][67233]
- [`Layout::new` is now `const`.][66254]
- [Added Standard Library support for `riscv64gc-unknown-linux-gnu`.][66899]
Stabilized APIs
---------------
- [`CondVar::wait_while`]
- [`CondVar::wait_timeout_while`]
- [`DebugMap::key`]
- [`DebugMap::value`]
- [`ManuallyDrop::take`]
- [`matches!`]
- [`ptr::slice_from_raw_parts_mut`]
- [`ptr::slice_from_raw_parts`]
Cargo
-----
- [You no longer need to include `extern crate proc_macro;` to be able to
`use proc_macro;` in the `2018` edition.][cargo/7700]
Compatibility Notes
-------------------
- [`Error::description` has been deprecated, and its use will now produce a
warning.][66919] It's recommended to use `Display`/`to_string` instead.
- [`use $crate;` inside macros is now a hard error.][37390] The compiler
emitted forward compatibility warnings since Rust 1.14.0.
- [As previously announced, this release reduces the level of support for
32-bit Apple targets to tier 3.][apple-32bit-drop]. This means that the
source code is still available to build, but the targets are no longer tested
and no release binary is distributed by the Rust project. Please refer to the
linked blog post for more information.

# Style Guide
## Prose
* Prefer title case for chapter/section headings, ex: `## Generating a Secret
Number` rather than `## Generating a secret number`.
* Prefer italics over single quotes when calling out a term, ex: `is an
*associated function* of` rather than `is an ‘associated function’ of`.
* When talking about a method in prose, DO NOT include the parentheses, ex:
`read_line` rather than `read_line()`.
* Hard wrap at 80 chars
* Prefer not mixing code and not-code in one word, ex: ``Remember when we wrote
`use std::io`?`` rather than ``Remember when we `use`d `std::io`?``
## Code
* Add the file name before markdown blocks to make it clear which file we're
talking about, when applicable.
* When making changes to code, make it clear which parts of the code changed
and which stayed the same... not sure how to do this yet
* Split up long lines as appropriate to keep them under 80 chars if possible
* Use `bash` syntax highlighting for command line output code blocks
## Links
Once all the scripts are done:
* If a link shouldn't be printed, mark it to be ignored
* This includes all "Chapter XX" intra-book links, which *should* be links
for the HTML version
* Make intra-book links and stdlib API doc links relative so they work whether
the book is read offline or on docs.rust-lang.org
* Use markdown links and keep in mind that they will be changed into `text at
*url*` in print, so word them in a way that it reads well in that format

Welcome to The Rust Programming Language book! This version of the text assumes
you are using Rust 1.31.0 or later, with `edition="2018"` in *Cargo.toml* of
all projects to use Rust 2018 Edition idioms. See the “Installation” section of
Chapter 1 to install or update Rust, and see the new Appendix E for information
on what editions of Rust are.
The 2018 Edition of the Rust language includes a number of improvements to make
Rust more ergonomic and easier to learn. This printing of the book has a number
of changes to reflect the improvements:
- Chapter 7, "Managing Growing Projects with Packages, Crates, and Modules",
has been mostly rewritten. The module system and the way paths work in the
2018 Edition have been made more consistent.
- Chapter 10 has new sections titled "Traits as Parameters" and "Returning
Types that Implement Traits" that explain the new `impl Trait` syntax.
- Chapter 11 has a new section "Using `Result<T, E>` in Tests" that shows how
to write tests that can use the `?` operator.
- The "Advanced Lifetimes" section of Chapter 19 has been removed as compiler
improvements have made the constructs in that section even more rare.
- The previous Appendix D on macros has been expanded to include procedural
macros, and has been moved to the "Macros" section in Chapter 19.
- Appendix A, "Keywords", also explains the new raw identifiers feature that
enables code written in Rust 2015 and Rust 2018 to interoperate.
- Appendix D now covers useful development tools that have been recently
released.
- We fixed a number of small errors and imprecise wording throughout the book.
Thank you to the readers who reported them!
Note that any code in the first printing of *The Rust Programming Language*
that compiled will continue to compile without `edition="2018"` in the
project's *Cargo.toml*, even as you update the version of the Rust compiler
that you're using. That's Rust's backwards compatibility guarantees at work!

(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents

do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Style Guide
## Prose
* Prefer title case for chapter/section headings, ex: `## Generating a Secret
Number` rather than `## Generating a secret number`.
* Prefer italics over single quotes when calling out a term, ex: `is an
*associated function* of` rather than `is an ‘associated function’ of`.
* When talking about a method in prose, DO NOT include the parentheses, ex:
`read_line` rather than `read_line()`.
* Hard wrap at 80 chars
* Prefer not mixing code and not-code in one word, ex: ``Remember when we wrote
`use std::io`?`` rather than ``Remember when we `use`d `std::io`?``
## Code
* Add the file name before markdown blocks to make it clear which file we're
talking about, when applicable.
* When making changes to code, make it clear which parts of the code changed
and which stayed the same... not sure how to do this yet
* Split up long lines as appropriate to keep them under 80 chars if possible
* Use `bash` syntax highlighting for command line output code blocks
## Links
Once all the scripts are done:
* If a link shouldn't be printed, mark it to be ignored
* This includes all "Chapter XX" intra-book links, which *should* be links
for the HTML version
* Make intra-book links and stdlib API doc links relative so they work whether
the book is read offline or on docs.rust-lang.org
* Use markdown links and keep in mind that they will be changed into `text at
*url*` in print, so word them in a way that it reads well in that format
