Overview
Go allows associating arbitrary behavior with built-in or custom types, which contributes to the object-oriented character of the language. Note that Go is not a fully object-oriented language, it misses type inheritance, for example.
Syntactically, the association of the behavior with the type is done by declaring a function, encapsulating the behavior we want to add to the type, and adding a receiver type to its signature:
func (t ReceiverType) FunctionName(parameters, ...) (return_declaration) {
...
}
As result of this association, the function becomes a method of the type.
