== cobalt/this_thread.hpp
|
|
|
|
Since everything is single threaded this library provides an executor
|
|
& default memory-resource for every thread.
|
|
|
|
[source,cpp]
|
|
----
|
|
namespace boost::cobalt::this_thread
|
|
{
|
|
|
|
pmr::memory_resource* get_default_resource() noexcept; // <1>
|
|
pmr::memory_resource* set_default_resource(pmr::memory_resource* r) noexcept; // <2>
|
|
pmr::polymorphic_allocator<void> get_allocator(); // <3>
|
|
|
|
typename asio::io_context::executor_type & get_executor(); // <4>
|
|
void set_executor(asio::io_context::executor_type exec) noexcept; // <5>
|
|
|
|
}
|
|
----
|
|
<1> Get the default resource - will be pmr::get_default_resource unless set
|
|
<2> Set the default resource - returns the previously set one
|
|
<3> Get an allocator wrapping (1)
|
|
<4> Get the executor of the thread - throws if not set
|
|
<5> Set the executor of the current thread.
|
|
|
|
The coroutines will use these as defaults, but keep a copy just in case.
|
|
|
|
NOTE: The only exception is the initialization of an cobalt-operation,
|
|
which will use the this_thread::executor to rethrow from. |
