final class single extends Annotation with SymbolArity

The default arity annotation. Usually there is no need to use this annotation explicitly.

When applied on raw method, there must be exactly one real method matching this raw method and it must have the same name (or rpcName) as raw method's name.

When applied on raw parameter, specifies that this raw parameter must be matched by exactly one real parameter, on the position that matches raw parameter's position. Names are ignored because - unlike methods - parameters are identified by their position in parameter list(s) rather than their name.

By default, single raw methods and parameters are verbatim which means that the real method must have exactly the same return type as raw method and real parameter must have exactly the same type as raw parameter.

When applied on method metadata parameter or parameter metadata parameter, the rules above apply in the same way except that real method/parameter type is matched against the type passed as T to TypedMetadata[T] by metadata class. For example, if method metadata class extends TypedMetadata[Unit] then Unit is assumed to be the result type of raw method that this metadata class represents. Similarly, when parameter metadata class extends TypedMetadata[Int] then raw parameter represented by this metadata class is assumed to be of type Int.

Finally, when applied on metadata parameter with reifyAnnot, that parameter is supposed to hold exactly one instance of an annotation of given type from real trait/method/param. If there is no such annotation available, compilation error will be raised.
