Build with Naz : newtype design pattern, and impl Into T for ergonomic APIs

This video shows how you can use newtype design pattern, and into Impl T. I use an example of building structs to do 2D layout and sizing without using newtype design pattern and demonstrate the pitfalls of using usize everywhere. Then convert it to use newtype pattern, into Impl T, to get all the benefits. Remove entire classes of problems from even existing, thanks to the Rust compiler.

Chapters:
00:00:00 Intro
00:06:04 Ex 1: Using usize for everything and the issues
00:19:35 Ex 2: Use newtype to create core types - X, Y, Width, Height
00:30:28 Ex 3: Use newtype to create Point & Size types
00:39:28 Ex 4: Use into Impl T for X, Y, Width, Height from usize, f64, etc
00:53:05 Ex 5: Use Add to add X & Y to make Point
01:02:05 Ex 6: Allow conversions between Width - X and Height - Y types
01:24:32 Ex 7: Impl Drop and newtype
