Member Functions

Name	Description
any_io_executor [constructor]	Default constructor. — Construct in an empty state. Equivalent effects to default constructor. — Copy constructor. — Move constructor. — Construct to point to the same target as another any_executor. — Construct a polymorphic wrapper for the specified executor.
context	Obtain the underlying execution context.
execute	Execute the function on the target executor.
operator bool	Determine whether the wrapper has a target executor.
operator=	Assignment operator. — Move assignment operator. — Assignment operator that sets the polymorphic wrapper to the empty state.
prefer	Obtain a polymorphic wrapper with the specified property.
query	Obtain the value associated with the specified property.
require	Obtain a polymorphic wrapper with the specified property.
swap	Swap targets with another polymorphic wrapper.
target	Get a pointer to the target executor.
target_type	Get the type of the target executor.
~any_io_executor [destructor]	Destructor.

The any_io_executor type is a polymorphic executor that supports the set of properties required by I/O objects. It is defined as the execution::any_executor class template parameterised as follows:

execution::any_executor<
  execution::context_as_t<execution_context&>,
  execution::blocking_t::never_t,
  execution::prefer_only<execution::blocking_t::possibly_t>,
  execution::prefer_only<execution::outstanding_work_t::tracked_t>,
  execution::prefer_only<execution::outstanding_work_t::untracked_t>,
  execution::prefer_only<execution::relationship_t::fork_t>,
  execution::prefer_only<execution::relationship_t::continuation_t>
