Platform Support

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.

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.
