Lifetimes

Just mark it with '_, 'a or 'static and hope one of them works was my first go-to solutions when dealign with rust borrow checker. I had no clue what lifetimes meant to represent, or how their values are inferred since unlike type generics there's not a single point where the type can be inferred from the context.

let mut values = Vec::new();
values.push(Route { path: "/home" });

There, the second line calls Vec::push(&mut self, value: T) function with a value of Route { path: "/home" } which is an instance of the type Route. There compiler can infer that the type argument T can be implicitly set to Route and fill the missing gaps for us. You might be thinking, what if you wanted to store different implementations of Route, aka how does it deal with inheritance. The answer is, we don't need to worry about that because rust doesn't have a concept of inheritance. As a matter of fact, it is completely unnecessary in this context, since we are dealing with data not
