Trait rustc_ap_rustc_target::abi::MaybeResult

pub trait MaybeResult<T> {
    type Error;
    pub fn from(x: Result<T, Self::Error>) -> Self;
    pub fn to_result(self) -> Result<T, Self::Error>;
}

The TyAndLayout above will always be a MaybeResult<TyAndLayout<'_, Self>>. We can't add the bound due to the lifetime, but this trait is still useful when writing code that's generic over the LayoutOf impl.
