Function design_pattern_examples_rust::strategy::strategy_exercise

pub fn strategy_exercise() -> Result<(), String>

Example of using the “Strategy” design pattern.

The Strategy pattern provides a way to easily assign different algorithms to an object instance that can be changed at the time the object is created.

In this exercise, the StrategyShowEntries instance sorts and displays a list of EntryInformation elements. Three different sorting strategies are provided (Name, Age, Height) and an option to reverse the normal order of the sort.
