Overview
An existing type can be used as the type specification of a new type.
Example:
type Duration int64
In the case above, Duration and int64 are considered two distinct and different types. Values of two types cannot assigned to each other, even if they are compatible.
The standard library uses this type declaration to create high-level functionality from built-in types.
