This group contains functions that you, as an abstraction developer, must implement. All functions that are deleted must be provided, functions that have a default implementation may be left unimplemented if the default behaviour is satisfactory. | |

Detailed Description
Namespace for the overloads and specializations that make up a SIMD implementation.
This namespace contains three sets of things: the struct ADLTag, which is used to look up functions in this namespace using argument-dependet lookup, traits classes that must be specialized by abstraction implementations, and functions that must/can be overloaded by abstraction implementations.
- Note
- Only introduce new names into this namespace to extend the interface. This applies in particular to people in the "abstraction developer" role; they may meddle in this namespace only by providing overloads and/or specializations for existing names (and for
ADLTag
even that is prohibited).

This binds to rvalues and const lvalues. It would bind to non-const lvalues too, but those are caught by the overload with ADLTag<3>. Using a universal reference here would bind to any argument with a perfect match. This would mean ambiguous overloads with other abstractions, if those only declare overloads for const TheirType &
and TheirType &
, because because universal references match perfectly.
