[Boost.MultiIndex](http://boost.org/libs/multi_index) provides a class template

named `multi_index_container` which enables the construction of containers

maintaining one or more indices with different sorting and access semantics.

## Learn about Boost.MultiIndex

* [Online documentation](https://boost.org/libs/multi_index)

## Install Boost.MultiIndex

* [Download Boost](https://www.boost.org/users/download/) and you're ready to go (this is a header-only library requiring no building).

* Using Conan 2: In case you don't have it yet, add an entry for Boost in your `conanfile.txt` (the example requires at least Boost 1.86):

```

[requires]

boost/[>=1.86.0]

```

If you're not using any compiled Boost library, the following will skip building altogether:


```

[options]

boost:header_only=True

```

* Using vcpkg: Execute the command

```

vcpkg install boost-multi-index

```

* Using CMake: [Boost CMake support infrastructure](https://github.com/boostorg/cmake)

allows you to use CMake directly to download, build and consume all of Boost or

some specific libraries.

## Support

* Join the **#boost** discussion group at [cpplang.slack.com](https://cpplang.slack.com/)

([ask for an invite](https://cppalliance.org/slack/) if you’re not a member of this workspace yet)

* Ask in the [Boost Users mailing list](https://lists.boost.org/mailman/listinfo.cgi/boost-users)

(add the `[multi_index]` tag at the beginning of the subject line)

* [File an issue](https://github.com/boostorg/multi_index/issues)

## Contribute

* [Pull requests](https://github.com/boostorg/multi_index/pulls) against **develop** branch are most welcome.
