问：当前Hardening面临的主要挑战是什么？ 答：Now that we've seen the problems with overlapping instances, let's look at the second coherence rule, which forbids orphan implementations. This restriction is most well-known for the following use case. On one hand, we have the serde crate, which defines the Serialize trait that is used pretty much everywhere. And then we have a library crate that defines a data type, say, a Person struct.

问：Hardening未来的发展方向如何？ 答：{ src = ./input.yaml; }
问：普通人应该如何看待Hardening的变化？ 答：Repairability forces better engineering discipline. It requires clarity, intentionality, and empathy for the people who will actually service and use the device over its lifetime.
问：Hardening对行业格局会产生怎样的影响？ 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.
面对Hardening带来的机遇与挑战，业内专家普遍建议采取审慎而积极的应对策略。本文的分析仅供参考，具体决策请结合实际情况进行综合判断。
