The interface {} type can be used to model structured data of any arbitrary schema in Go, such as JSON or YAML data, by representing it as a map [string] interface {} (map of string to empty interface). This recursively describes data in the form of a dictionary with string keys and values of any type.
The marker interface pattern is a design pattern in computer science, used with languages that provide run-time type information about objects.It provides a means to associate metadata with a class where the language does not have explicit support for such metadata.
The primary function of a foreign function interface is to mate the semantics and calling conventions of one programming language (the host language, or the language which defines the FFI), with the semantics and conventions of another (the guest language).

The guidelines further recommend that the name given to an interface be PascalCase preceded by the capital letter I, as in IEnumerable. The Microsoft guidelines for naming fields are specific to static , public , and protected fields; fields that are not static and that have other accessibility levels (such as internal and private ) are ...
Similarly, the result type IEnumerator < T > of GetEnumerator must be valid covariantly, i.e. (since IEnumerator is a covariant interface) the type T must be valid covariantly, i.e. the type parameter T must not be tagged in. This shows that the interface IList is not allowed to be marked either co- or contravariant.
Donald Trump has doubled down on his ambition to buy Greenland using economic or military pressure. Residents of its capital of Nuuk are unhappy about it.
Interface injection, where the dependency's interface provides an injector method that will inject the dependency into any client passed to it. In some frameworks, clients do not need to actively accept dependency injection at all. In Java, for example, reflection can make private attributes public when testing and inject services directly.
