Casting a number from one type to another: the trait bound `usize: From` is not satisfied
I have a function that gets the dimensions of an image, and in different scenarios, I would it to be cast from a u32 to another number type suchas usize, i32, etc. However, when I try to do the following in get_dimensions it doesn’t work. Is something like this possible? I looked at How do I convert between numeric types safely and idiomatically? but in that example it uses an explicit type such as i32::from(...) whereas I would hopefully like to use a dynamic type.
How to use read_line so that it replace the contents of the buffer given instead of appending to it?
My first program in Rust is supposed to take input from the user in the form of characters, either C or F:

How do you access enum values in Rust?
struct Point { x: f64, y: f64, } enum Shape { Circle(Point, f64), Rectangle(Point, Point), } let my_shape = Shape::Circle(Point { x: 0.0, y: 0.0 }, 10.0); I want to print out circle‘s second property, which is 10.0 here. I tried my_shape.last and my_shape.second, but neither worked. What should I do in order to print […]
