x86_64-uwp-windows-msvc, i686-uwp-windows-msvc, thumbv7a-uwp-windows-msvc and aarch64-uwp-windows-msvc
Tier: 3
Windows targets for Universal Windows Platform (UWP) applications, using MSVC toolchain.
Target maintainers
Requirements
These targets are cross-compiled with std support. The host requirement and
binary format are the same as the corresponding non-UWP targets (i.e.
x86_64-pc-windows-msvc, i686-pc-windows-msvc, thumbv7a-pc-windows-msvc
and aarch64-pc-windows-msvc).
Building the targets
The targets can be built by enabling them for a rustc build, for example:
[build]
build-stage = 1
target = ["x86_64-uwp-windows-msvc", "aarch64-uwp-windows-msvc"]
Building Rust programs
Rust does not yet ship pre-compiled artifacts for these targets. To compile for
these targets, you will either need to build Rust with the targets enabled (see
"Building the targets" above), or build your own copy of std by using
build-std or similar.
Example of building a Rust project for x64 UWP using build-std:
cargo build -Z build-std=std,panic_abort --target x86_64-uwp-windows-msvc
Testing
Currently there is no support to run the rustc test suite for this target.
Cross-compilation toolchains and C code
In general, the toolchain target should match the corresponding non-UWP targets. Beware that not all Win32 APIs behave the same way in UWP, and some are restricted in AppContainer or even not available at all. If the C code being compiled happens to use any of restricted or unavailable APIs, consider using allowed alternatives or disable certain feature sets to avoid using them.
