Welcome to Day 3

Today, we will cover some more advanced topics of Rust:

• Traits: deriving traits, default methods, and important standard library traits.

• Generics: generic data types, generic methods, monomorphization, and trait objects.

• Error handling: panics, Result, and the try operator ?.

• Testing: unit tests, documentation tests, and integration tests.

• Unsafe Rust: raw pointers, static variables, unsafe functions, and extern functions.
