Anything has a state. An entity has a state. Similarly, a car can be in a state of acceleration. While it is accelerating, there are some things it certainly cannot or should not do, e.g., reversing at that very moment. The State Design Pattern treats each state as a struct whose functions represent movements to the other states. Continue Reading
This Design Pattern uses commands to wrap and invoke capabilities. A car can run faster and slower. We can have commands AccelerateCommand and DecelerateCommand for increasing and decreasing speed, respectively. We can also have AccelerateAndDecelerateCommand to run both capabilities in a certain order. Continue Reading
This Design Pattern replaces a behavior with different implementation at run-time or sometimes at load-time by means of configuration. Two entities could have different implementations of the same behavior. Continue Reading
In this post, we want to create a Vec instance that only accepts struct instances that implements a particular trait. Continue Reading
This post briefly talks about how to create functions that accept struct instances that implement a specific trait. Continue Reading
This post provides an example the uses async, async fn, and await for asynchronous processing. The sample codes use the futures crate to block the main function until the asynchronous function completes execution. Continue Reading
Merge Sort is an algorithm invented by John von Neumann in 1945 and it is one of the most efficient sorting algorithms. It uses the principle of divide-and-conquer. Continue Reading
This post is about an example of the Quicksort algorithm in Rust. It sorts an array of i32 with 13 elements. Continue Reading
