Generics allow you to abstract a function so that it accepts a range of types.
Functions, Structs, Enums etc. can all be expressed as generics

Example

// everywhere 'T' shows up, it represents the type.
struct Coord<T> {
    x: T,
    y: T,
    z: T,
}

let c = Coord{1, 2, 3};   // valid
let c = Coord{1, 2u8, 3}; // invalid! 1/3 are i32, but 2u8 is a u8.
