&lt;/code&gt;&lt;/pre&gt;
You can then “cargo +nightly miri test” to run your tests under miri. You probably should “cargo clean” first.&lt;p&gt;Of course you can skip the explicit nightly flags in those commands if your default toolchain is nightly.</text><parent_chain></parent_chain></comment><story><title>Miri: Interpreter for Rust&apos;s mid-level intermediate representation</title><url>https://github.com/rust-lang/miri</url></story>
