Platform Support
Support for different platforms ("targets") are organized into three tiers, each with a different set of guarantees. For more information on the policies for targets at each tier, see the Target Tier Policy.
Targets are identified by their "target triple" which is the string to inform the compiler what kind of output should be produced.
Tier 1 with Host Tools
Tier 1 targets can be thought of as "guaranteed to work". The Rust project builds official binary releases for each tier 1 target, and automated testing ensures that each tier 1 target builds and passes tests after each change.
Tier 1 targets with host tools additionally support running tools like rustc
and cargo natively on the target, and automated testing ensures that tests
pass for the host tools as well. This allows the target to be used as a
development platform, not just a compilation target. For the full requirements,
see Tier 1 with Host Tools in
the Target Tier Policy.
All tier 1 targets with host tools support the full standard library.

Tier 1
Tier 1 targets can be thought of as "guaranteed to work". The Rust project builds official binary releases for each tier 1 target, and automated testing ensures that each tier 1 target builds and passes tests after each change. For the full requirements, see Tier 1 target policy in the Target Tier Policy.
At this time, all Tier 1 targets are Tier 1 with Host Tools.
Tier 2 with Host Tools
Tier 2 targets can be thought of as "guaranteed to build". The Rust project builds official binary releases for each tier 2 target, and automated builds ensure that each tier 2 target builds after each change. Automated tests are not always run so it's not guaranteed to produce a working build, but tier 2 targets often work to quite a good degree and patches are always welcome!
Tier 2 targets with host tools additionally support running tools like rustc
and cargo natively on the target, and automated builds ensure that the host
tools build as well. This allows the target to be used as a development
platform, not just a compilation target. For the full requirements, see Tier 2
with Host Tools in the Target
Tier Policy.
All tier 2 targets with host tools support the full standard library.

Tier 3
Tier 3 targets are those which the Rust codebase has support for, but which the Rust project does not build or test automatically, so they may or may not work. Official builds are not available. For the full requirements, see Tier 3 target policy in the Target Tier Policy.
The std column in the table below has the following meanings:
- ✓ indicates the full standard library is available.
- * indicates the target only supports
no_stddevelopment. - ? indicates the standard library support is unknown or a work-in-progress.
The host column indicates whether the codebase includes support for building
host tools.
