Methods on a struct in Rust
Rust interview exercise on Structs & Enums, difficulty 1 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Implement three items on Rectangle: square(size), an associated function that builds a square; area(&self); and can_hold(&self, other), true only when other is strictly smaller in both width and height.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Progress is saved in your browser, and in your account if you sign in.
