 We can also see that it uses the `ScalarPair` abi which is relevant for Miri and when passing data as arguments to another function.
 To learn more about what all this information means, see [the `Layout` type docs](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_target/abi/struct.Layout.html).

 So the next time you work with `Layout` and wonder how exactly the niche gets represented, or whether an `enum` can have `ScalarPair` abi (hint: yes it can), you can easily look at a few examples to see how rustc thinks about this type internally.
 This is basically the type-level equivalent of `--emit mir`.
