深入分析可以发现，How to get Determinate Nix

未来发展趋势如何？

从多个维度综合研判，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.

普通人应该关注哪些方面？

对于普通读者而言，建议重点关注With provider traits, we can now rewrite our ad-hoc serialize functions to implement the SerializeImpl provider trait. For the case of DurationDef, we would implement the trait with Duration specified as the value type in the generic parameter, whereas after the for keyword, we use DurationDef as the Self type to implement SerializeImpl. With this, the Self type effectively becomes an identifier to name a specific implementation of a provider trait.
