Generic Cache System

Build a simple key-value cache that can store any types. You'll write generic functions that manage cached data, demonstrating how generics let you write one implementation that works with strings, numbers, or any other type.

What you'll practice

• Writing generic functions with multiple type parameters <K, V>
• Using trait bounds to constrain what types can be used
• Working with HashMap<K, V> and generic collections
• Combining Option<T> and Result<T, E> with generics
