许多读者来信询问关于First ‘hal的相关问题。针对大家最为关心的几个焦点，本文特邀专家进行权威解读。
问：关于First ‘hal的核心要素，专家怎么看？ 答：The Rust book gives us a great high-level description of traits, focusing on the idea of shared behavior. On one hand, traits allow us to implement these behaviors in an abstract way. On the other, we can use trait bounds and generics to work with any type that provides a specific behavior. This essentially gives us an interface to decouple the code that uses a behavior from the code that implements it. But, as the book also points out, the way traits work is quite different from the concept of interfaces in languages like Java or Go.

问：当前First ‘hal面临的主要挑战是什么？ 答：There are good reasons why Rust cannot feasibly detect and replace all blanket implementations with specialized implementations during instantiation. This is because a function like get_first_value can be called by other generic functions, such as the print_first_value function that is defined here. In this case, the fact that get_first_value uses Hash becomes totally obscured, and it would not be obvious that print_first_value indirectly uses it by just looking at the generic trait bound.
