associated_immediate

associated_immediate_executor

Traits type used to obtain the immediate executor associated with an object.

template<
    typename T,
    typename Executor>
struct associated_immediate_executor

Types

Name	Description
type	If T has a nested type immediate_executor_type,.

Member Functions

Name	Description
decltype [static]	If T has a nested type immediate_executor_type, returns t.get_immediate_executor(). Otherwise returns boost::asio::require(ex, boost::asio::execution::blocking.never).

Data Members

Name	Description
noexcept

A program may specialise this traits type if the T template parameter in the specialisation is a user-defined type. The template parameter Executor shall be a type meeting the Executor requirements.

Specialisations shall meet the following requirements, where t is a const reference to an object of type T, and e is an object of type Executor.

Provide a nested typedef type that identifies a type meeting the Executor requirements.
Provide a noexcept static member function named get, callable as get(t) and with return type type or a (possibly const) reference to type.
Provide a noexcept static member function named get, callable as get(t,e) and with return type type or a (possibly const) reference to type.
