Hands-on Rust: Explain coordinates (page 50)
I think it would be beneficial to shortly explain how the “screen-space coordinates” work or that the proposed system is some sort of simplification. Because the book instructs to create 80x50 window, but how many pixels is the height ? is it 200 or maybe 500 ? i noticed that the set method of console mentions cell, but what is it ?
