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.
Component availability is tracked here.
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 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 targets can be thought of as "guaranteed to build". The Rust project
builds official binary releases of the standard library (or, in some cases,
only the core library) for each tier 2 target, and automated builds
ensure that each tier 2 target can be used as build target 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 target-specific code is not closely scrutinized by Rust team(s) when modifications are made. Bugs are possible in all code, but the level of quality control for these targets is likely to be lower. See library team policy for details on the review practices for standard library code.
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.
NOTE: The rust-docs component is not usually built for tier 2 targets,
so Rustup may install the documentation for a similar tier 1 target instead.

Tier 2 targets can be thought of as "guaranteed to build". The Rust project
builds official binary releases of the standard library (or, in some cases,
only the core library) for each tier 2 target, and automated builds
ensure that each tier 2 target can be used as build target 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! For
the full requirements, see Tier 2 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 a work-in-progress.
Tier 2 target-specific code is not closely scrutinized by Rust team(s) when modifications are made. Bugs are possible in all code, but the level of quality control for these targets is likely to be lower. See library team policy for details on the review practices for standard library code.
NOTE: The rust-docs component is not usually built for tier 2 targets,

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.
Tier 3 target-specific code is not closely scrutinized by Rust team(s) when modifications are made. Bugs are possible in all code, but the level of quality control for these targets is likely to be lower. See library team policy for details on the review practices for standard library code.
The host column indicates whether the codebase includes support for building
host tools.

Due to limitations of the C ABI, floating-point support on
i686targets is non-compliant: floating-point return values are passed via an x87 register, so NaN payload bits can be lost. Functions with the default Rust ABI are not affected. See issue #115567. ↩ ↩2 ↩3 ↩4 ↩5 ↩6 ↩7 ↩8 ↩9 ↩10 ↩11 ↩12 ↩13 ↩14 ↩15 ↩16 ↩17 ↩18 -
Floating-point support on
i586targets is non-compliant: thex87registers and instructions used for these targets do not provide IEEE-754-compliant behavior, in particular when it comes to rounding and NaN payload bits. See issue #114479. ↩ ↩2 ↩3
