Expressing complex concepts almost always requires complex expressions of intent! I don’t really know Rust all that well beyond a few toy projects. But if you were familiar with core aspects of the syntax and semantics - lifetimes, generics, tuples and the void type in this case - then it’s not particularly complex. Add to the fact that it’s code you’re not actually going to see in practice and I don’t think it’s so bad!
