* Structs

A `struct` is a collection of fields.
A `struct` is a typed collection of fields. In Go, structs are the way to create user-defined concrete types.
Syntax to create a struct starts with the keyword `type`, then a name for the struct, followed by the `struct` keyword.
Inside curly backets, collection of fields are specified with field name and field type.

The `type` keyword is used to define a new type in Go. It is generally referred as [[https://golang.org/ref/spec#Type_definitions][type definition]].

In the given example, a new struct type `Vertex` is created which consist of fields `X` & `Y` of type `int`.

*Note:* Data field in a struct is declared with a known type, which could be a built-in type or a user-defined type.
