+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the 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
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      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
+      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
+          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
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          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
+          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
+      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.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      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,
+      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.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+> MAC address types for Rust
+
+[![Latest Version](https://img.shields.io/crates/v/macaddr.svg)](https://crates.io/crates/macaddr)
+[![Latest Version](https://docs.rs/macaddr/badge.svg)](https://docs.rs/macaddr)
+[![Build Status](https://github.com/svartalf/rust-macaddr/workflows/Continuous%20integration/badge.svg)](https://github.com/svartalf/rust-macaddr/actions)
+[![Coverage Status](https://coveralls.io/repos/github/svartalf/rust-macaddr/badge.svg?branch=master)](https://coveralls.io/github/svartalf/rust-macaddr?branch=master)
+![Minimum rustc version](https://img.shields.io/badge/rustc-1.31+-green.svg)
+![Apache 2.0 OR MIT licensed](https://img.shields.io/badge/license-Apache2.0%2FMIT-blue.svg)
+![unsafe forbidden](https://img.shields.io/badge/unsafe-forbidden-success.svg)
+
+This crate provides types for a [MAC address](https://en.wikipedia.org/wiki/MAC_address)
+identifiers, both in IEEE *EUI-48* and *EUI-64* formats.
+
+It is like a [`std::net::SocketAddr`](https://doc.rust-lang.org/std/net/enum.SocketAddr.html) enum with a
+[`std::net::SocketAddrV4`](https://doc.rust-lang.org/std/net/struct.SocketAddrV4.html) and
+[`std::net::SocketAddrV6`](https://doc.rust-lang.org/std/net/struct.SocketAddrV6.html) members,
+but for MAC addresses instead.
+
+Obviously, MAC address can be represented as a `[u8; 6]` or `[u8; 8]`,
+but it is error-prone and inconvenient, so here they are —
+[MacAddr6](https://docs.rs/macaddr/latest/macaddr/struct.MacAddr6.html) and
+[MacAddr8](https://docs.rs/macaddr/latest/macaddr/struct.MacAddr8.html)
+structs with helpful methods and standard Rust traits implementations,
+intended to be the first-class Rust objects.
+
+And it is `serde`- and `no_std`-friendly also!
+
+## Installation
+
+Add this to your `Cargo.toml`
+
+```toml
+[dependencies]
+macaddr = "1.0"
+```
+
+## Usage
+
+Check out the [documentation](https://docs.rs/macaddr) for each type
+available, all of them have a plenty of examples.
+
+## License
+
+Licensed under either of [Apache License 2.0](https://github.com/svartalf/rust-macaddr/blob/master/LICENSE-APACHE)
+or [MIT license](https://github.com/svartalf/rust-macaddr/blob/master/LICENSE-MIT) at your option.
+
+Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in this crate by you,
+as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.

+//! This crate provides types for a [MAC address] identifiers,
+//! both in IEEE *EUI-48* and *EUI-64* formats.
+//!
+//! It is like a `std::net::SocketAddr` enum
+//! with `std::net::SocketAddrV4` and `std::net::SocketAddrV6` members,
+//! but for MAC addresses instead.
+//!
+//! Obviously, MAC address can be represented as a `[u8; 6]` or `[u8; 8]`,
+//! but it is error-prone and inconvenient, so here they are —
+//! [MacAddr6] and [MacAddr8] structs with helpful methods and
+//! standard Rust traits implementations to make them first-class
+//! Rust objects.
+//!
+//! ## Serde support
+//!
+//! [Serde] support can be enabled with a `"serde_std"` feature
+//! (disabled by default) if used in `std`-enabled builds.
+//!
+//! This feature is called like this because of [this Cargo bug].\
+//! `"serde"` feature is exists also, but it is intended to be used
+//! in the `no_std` builds.
+//!
+//! ## No-std support
+//!
+//! This crate can be used in a `no_std` builds with
+//! disabled `"std"` feature (enabled by default).
+//!
