What are traits and how are they different from interfaces?

Traits are pieces of functionality shared across components. They can contain code as well as associated types, and can be implemented for any type and generics independently. Interfaces, on the other hand, describe the public methods a class provides, without an implementation and typically with inheritance. Rust only has traits.

Why doesn't Rust have a garbage collector?

Garbage collection is required to free up unused heap memory that is generated from a running the program. Rust avoids this by providing a static code analysis at compile-time that forces the user to think of variable lifetimes. These lifetimes are very strictly defined and require a lifetime scope to own or borrow memory so that the compiler knows when it's not being used without an explicit statement.
