Struct template closure

boost::stl_interfaces::closure

Synopsis

// In header: <boost/stl_interfaces/view_adaptor.hpp>

template<typename F> 
struct closure :
  public boost::stl_interfaces::range_adaptor_closure< closure< F > >
{

  // public member functions
  closure(F);
  template<typename T, typename Enable = unspecified> 
    constexpr decltype(auto) operator()(T &&) const;
  template<typename T, typename Enable = unspecified> 
    constexpr decltype(auto) operator()(T &&);
};

Description

An invocable consisting of a contained invocable f. Calling operator() with some argument t calls f(t) and returns the result. This type is typically used to capture a the result of a call to bind_back().

`closure` public member functions

```
closure(F f);
```

template<typename T, typename Enable = unspecified> 
  constexpr decltype(auto) operator()(T && t) const;

template<typename T, typename Enable = unspecified> 
  constexpr decltype(auto) operator()(T && t);
