{"version":"1.0","type":"rich","title":"My activities in http://rustbyexample.com/","description":"This example shows how the Rust programming language handles tuples, structs, and custom formatting through a series of exercises from the Rust by Example tutorial. It demonstrates tuple indexing, destructuring, and reversal, plus a Matrix tuple struct with a custom `fmt::Display` implementation that prints it as a two-line grid. It also defines Point and Rectangle structs, computes rectangle area via destructuring, and creates a square from a point and side length. The code uses Rust’s standard `std::fmt` module and the `#[derive(Debug)]` attribute for debug output.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-d3c180bf7a3b20af852a8ccab27549f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
