Prerequisites

Before you install Slint SC, make sure your host has the following software packages installed.

Rust Toolchain

You must build your application with a Rust toolchain that’s qualified for ISO 26262 ASIL B or higher. The runtime and the generated code ship as source, so your toolchain compiles them, not ours.

The toolchain has to support Rust 1.95 or later. The runtime is no_std and doesn’t allocate, so it builds for any target your toolchain supports, bare metal included.

The guide uses Cargo to build the application.

Coverage Measurement

To measure the coverage of your .slint code, you also need these on the host:

• llvm-cov and llvm-profdata, the LLVM tools that match your Rust toolchain.
• cargo-llvm-cov ↗, which runs your tests with coverage instrumentation.
• Optionally, genhtml from lcov ↗, to render the result as HTML.

The measurement runs on the host, not on the bare-metal target. To learn what that means for your evidence, see Coverage of Slint Code.
