Types

type Immutable

type Immutable interface {
	// Prev is the previous element on a chain.
	Prev() Immutable
	// Fn a function that is able to modify the passed element.
	Fn(interface{}) error
	// Base is the first element on a chain, there's no previous element before
	// the Base element.
	Base() interface{}
}

Immutable represents an immutable chain that, if passed to FastForward, applies Fn() to every element of a chain, the first element of this chain is represented by Base().
