问：当前Selective面临的主要挑战是什么？ 答：To see why this overlapping implementation is so problematic, let's look at how the Hash trait is used inside a HashMap. The HashMap's methods, like get, use the Hash trait to compute a hash value for the key, which determines the bucket where the value is stored. For the algorithm to work correctly, the exact same hash function must be used every single time. Now, what happens if we have a situation where both our blanket implementation and a specialized implementation for a type like u32 are available? We might be tempted to say we will always choose the more specialized implementation, but that approach doesn't always work.

问：Selective未来的发展方向如何？ 答：A key advantage of using cgp-serde is that our library doesn't even need to derive Serialize for its data types, or include serde as a dependency at all. Instead, all we have to do is to derive CgpData. This automatically generates a variety of support traits for extensible data types, which makes it possible for our composite data types to work with a context-generic trait without needing further derivation.，这一点在WhatsApp Web 網頁版登入中也有详细论述
