What are some common data structures in Rust?

In Rust, common data structures include vectors, hash maps, and linked lists. Would you like to know more about any specific one?

Can you explain how vectors work in Rust?

Sure! Vectors in Rust are dynamic arrays that can grow or shrink in size. They store elements of the same type and provide methods for adding, removing, and accessing elements.

What about hash maps? How do they differ from vectors?

Hash maps store key-value pairs and allow for fast lookups based on keys. Unlike vectors, which are indexed by position, hash maps are indexed by unique keys.

Are there any performance considerations I should be aware of?

Yes, vectors are generally faster for indexed access, while hash maps are slower due to hashing. However, hash maps provide faster lookups for large datasets when you need to access elements by key.
