## Building Rust programs
Rust does not yet ship pre-compiled artifacts for this target. To compile for
this target, you will either need to build Rust with the target enabled (see
"Building the target" above), or build your own copy of `core` by using
`build-std` or similar.
Starting with Rust 1.62, precompiled artifacts are provided via `rustup`:
```text
# install cross-compile toolchain
rustup target add x86_64-unknown-none
# target flag may be used with any cargo or rustc command
cargo build --target x86_64-unknown-none
```
## Testing
As `x86_64-unknown-none` supports a variety of different environments and does
not support `std`, this target does not support running the Rust testsuite.
not support `std`, this target does not support running the Rust test suite.
