# Platform Support

<style type="text/css">

Support for different platforms are organized into three tiers, each with a
different set of guarantees.

Platforms are identified by their "target triple" which is the string to
inform the compiler what kind of output should be produced. The columns in the
tables below have the following meanings:

* std:
    * ✓ indicates the full standard library is available.
    * \* indicates the target only supports [`no_std`] development.
    * ? indicates the standard library support is unknown or a work-in-progress.
* host: A ✓ indicates that `rustc` and `cargo` can run on the host platform.

[`no_std`]: https://rust-embedded.github.io/book/intro/no-std.html

## Tier 1

Tier 1 platforms can be thought of as "guaranteed to work".
Specifically they will each satisfy the following requirements:

* Official binary releases are provided for the platform.
* Automated testing is set up to run tests for the platform.
* Landing changes to the `rust-lang/rust` repository's master branch is gated
  on tests passing.
* Documentation for how to use and how to build the platform is available.

## Tier 2

Tier 2 platforms can be thought of as "guaranteed to build". Automated tests
are not run so it's not guaranteed to produce a working build, but platforms
often work to quite a good degree and patches are always welcome!
Specifically, these platforms are required to have each of the following:

* Official binary releases are provided for the platform.
* Automated building is set up, but may not be running tests.
* Landing changes to the `rust-lang/rust` repository's master branch is gated on
    platforms **building**. For some platforms only the standard library is
    compiled, but for others `rustc` and `cargo` are too.

## Tier 3

Tier 3 platforms are those which the Rust codebase has support for, but which
are not built or tested automatically, and may not work. Official builds are
not available.
