Summary

In this chapter, we have implemented get_post() and get_posts() to show Post information in a web browser. Along with those implementations, we have learned about reducing code duplication through generics and trait bounds.

We have also learned about the most distinct and important feature of Rust: its memory model. We now know an instance owns a memory block, either in the stack or in both the stack and heap. We have also learned that assigning another instance to an instance means moving ownership unless it's a simple type that implements the Copy and/or Clone trait. We have also learned about borrowing, the rules of borrowing, and the use of the lifetime specifier to complement moving, copying, and borrowing.

Those rules are some of the most confusing parts of Rust, but those rules are also what make Rust a very safe language while still having the same performance as other system languages such as C or C++. Now that we have implemented showing posts, let&apos...
