sqt::BinderType Concept Reference

#include <sqt/orm/expression/binder/binder_type.h>

Description

Constrains a type to be a binder type, which provides information for binding values to a placeholder of an executor.

Requirements

• The type must have a nested type ValueType.
• The type must have a nested type ValueTraits.
• The type must have a member method Index() with the following signature:

  int Index() const noexcept;

The sqt::Binder<> class template satisfies this concept.
