    Qualify this binding key with the given name.

    Qualify this binding key with the given name.

    For example, you may have both a cached implementation, and a direct implementation of a service. To differentiate between them, you may decide to name the cached one:

    bind[Foo].qualifiedWith("cached").to[FooCached],
    bind[Foo].to[FooImpl]
    
    ...
    
    class MyController @Inject() (@Named("cached") foo: Foo) {
      ...
    }

    In the above example, the controller will get the cached Foo service.

    Qualify this binding key with the given annotation.

    Qualify this binding key with the given annotation.

    For example, you may have both a cached implementation, and a direct implementation of a service. To differentiate between them, you may define a Cached annotation:

    import scala.annotation._
    
    @target.param
    class Cached extends StaticAnnotation
    
    ...
    
    bind[Foo].qualifiedWith[Cached].to[FooCached],
    bind[Foo].to[FooImpl]
    
    ...
    
    class MyController @Inject() (@Cached foo: Foo) {
      ...
    }

    In the above example, the controller will get the cached Foo service.

    import scala.annotation._

    bind[Foo].to[FooImpl]
    
    ...
    
    class MyController @Inject() (@Cached foo: Foo) {
      ...
    }

    In the above example, the controller will get the cached Foo service.
