-[![Build Status](https://api.travis-ci.com/dtolnay/remain.svg?branch=master)](https://travis-ci.com/dtolnay/remain)
-[![Latest Version](https://img.shields.io/crates/v/remain.svg)](https://crates.io/crates/remain)
-[![Rust Documentation](https://img.shields.io/badge/api-rustdoc-blue.svg)](https://docs.rs/remain)
-
-This crate provides an attribute macro to check at compile time that the
-variants of an enum or the arms of a match expression are written in sorted
-order.
-
-```toml
-[dependencies]
-remain = "0.1"
-```
-
-## Syntax
-
-Place a `#[remain::sorted]` attribute on enums, structs, match-expressions, or
-let-statements whose value is a match-expression.
-
-Alternatively, import as `use remain::sorted;` and use `#[sorted]` as the
-attribute.
-
-```rust
-#[remain::sorted]
-#[derive(Debug)]
-pub enum Error {
-    BlockSignal(signal::Error),
-    CreateCrasClient(libcras::Error),
-    CreateEventFd(sys_util::Error),
-    CreateSignalFd(sys_util::SignalFdError),
-    CreateSocket(io::Error),
-    DetectImageType(qcow::Error),
-    DeviceJail(io_jail::Error),
-    NetDeviceNew(virtio::NetError),
-    SpawnVcpu(io::Error),
-}
-
-#[remain::sorted]
-#[derive(Debug)]
-pub enum Registers {
-    ax: u16,
-    cx: u16,
-    di: u16,
-    si: u16,
-    sp: u16,
-}
-
-impl Display for Error {
-    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
-        use self::Error::*;
-
-        #[remain::sorted]
-        match self {
-            BlockSignal(e) => write!(f, "failed to block signal: {}", e),
-            CreateCrasClient(e) => write!(f, "failed to create cras client: {}", e),
-            CreateEventFd(e) => write!(f, "failed to create eventfd: {}", e),
-            CreateSignalFd(e) => write!(f, "failed to create signalfd: {}", e),
-            CreateSocket(e) => write!(f, "failed to create socket: {}", e),
-            DetectImageType(e) => write!(f, "failed to detect disk image type: {}", e),
-            DeviceJail(e) => write!(f, "failed to jail device: {}", e),
-            NetDeviceNew(e) => write!(f, "failed to set up virtio networking: {}", e),
-            SpawnVcpu(e) => write!(f, "failed to spawn VCPU thread: {}", e),
-        }
-    }
-}
-```
-
-If an enum variant, struct field, or match arm is inserted out of order,
-
-```diff
-      NetDeviceNew(virtio::NetError),
-      SpawnVcpu(io::Error),
-+     AaaUhOh(Box<dyn StdError>),
-  }
-```
-
-then the macro produces a compile error.
-
-```console
-error: AaaUhOh should sort before BlockSignal
-  --> tests/stable.rs:49:5
-   |
-49 |     AaaUhOh(Box<dyn StdError>),
-   |     ^^^^^^^
-```
-
-## Compiler support
-
-The attribute on enums and structs is supported on any rustc version 1.31+.
-
-Rust does not yet have stable support for user-defined attributes within a
-function body, so the attribute on match-expressions and let-statements requires
-a nightly compiler and the following two features enabled:
-
-```rust
-#![feature(proc_macro_hygiene, stmt_expr_attributes)]
-```
-
-As a stable alternative, this crate provides a function-level attribute called
-`#[remain::check]` which makes match-expression and let-statement attributes
-work on any rustc version 1.31+. Place this attribute on any function containing
-`#[sorted]` to make them work on a stable compiler.
-
-```rust
-impl Display for Error {
-    #[remain::check]
-    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
-        use self::Error::*;
-
-        #[sorted]
-        match self {
-            /* ... */
-        }
-    }
-}

-   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-   copyright license to reproduce, prepare Derivative Works of,

-   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.
-

-   Work or Derivative Works thereof in any medium, with or without
-   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

-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       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
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution

-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.

-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,

-   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

-   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.
