29			/** CRTP mixin that adds I/O awaitable support to a promise type.
30
31			Inherit from this class to enable these capabilities in your coroutine:
32
33			1. Frame allocation — The mixin provides `operator new/delete` that
34			use the thread-local frame allocator set by `run_async`.
35
36			2. Environment storage — The mixin stores a pointer to the `io_env`
37			containing the executor, stop token, and allocator for this coroutine.
38
39			3. Environment access — Coroutine code can retrieve the environment
40			via `co_await this_coro::environment`, or individual fields via
41			`co_await this_coro::executor`, `co_await this_coro::stop_token`,
42			and `co_await this_coro::allocator`.
43
44			@tparam Derived The derived promise type (CRTP pattern).
45
46			@par Basic Usage
47
48			For coroutines that need to access their execution environment:
49
50			@code
51			struct my_task
52			{
53			struct promise_type : io_awaitable_promise_base<promise_type>
54			{
55			my_task get_return_object();
56			std::suspend_always initial_suspend() noexcept;
57			std::suspend_always final_suspend() noexcept;
58			void return_void();
59			void unhandled_exception();
60			};
61
62			// ... awaitable interface ...
63			};
64
65			my_task example()
66			{
67			auto env = co_await this_coro::environment;
68			// Access env->executor, env->stop_token, env->allocator
69
70			// Or use fine-grained accessors:
71			auto ex = co_await this_coro::executor;
72			auto token = co_await this_coro::stop_token;
73			auto* alloc = co_await this_coro::allocator;
74			}
75			@endcode
76
77			@par Custom Awaitable Transformation
78
79			If your promise needs to transform awaitables (e.g., for affinity or
80			logging), override `transform_awaitable` instead of `await_transform`:
81
82			@code
83			struct promise_type : io_awaitable_promise_base<promise_type>
84			{
85			template<typename A>
86			auto transform_awaitable(A&& a)
87			{
88			// Your custom transformation logic
89			return std::forward<A>(a);
90			}
91			};
92			@endcode
93
94			The mixin's `await_transform` intercepts @ref this_coro::environment_tag
95			and the fine-grained tag types (@ref this_coro::executor_tag,
96			@ref this_coro::stop_token_tag, @ref this_coro::allocator_tag),
97			then delegates all other awaitables to your `transform_awaitable`.
98
99			@par Making Your Coroutine an IoAwaitable
100
101			The mixin handles the "inside the coroutine" part—accessing the
102			environment. To receive the environment when your coroutine is awaited
103			(satisfying @ref IoAwaitable), implement the `await_suspend` overload
104			on your coroutine return type:
105
106			@code
107			struct my_task
108			{
109			struct promise_type : io_awaitable_promise_base<promise_type> { ... };
110
111			std::coroutine_handle<promise_type> h_;
112
113			// IoAwaitable await_suspend receives and stores the environment
114			std::coroutine_handle<> await_suspend(std::coroutine_handle<> cont, io_env const* env)
115			{
116			h_.promise().set_environment(env);
117			// ... rest of suspend logic ...
118			}
119			};
120			@endcode
121
122			@par Thread Safety
123			The environment is stored during `await_suspend` and read during
124			`co_await this_coro::environment`. These occur on the same logical
125			thread of execution, so no synchronization is required.
126
127			@see this_coro::environment, this_coro::executor,
128			this_coro::stop_token, this_coro::allocator
129			@see io_env
130			@see IoAwaitable
131			*/
132			template<typename Derived>
133			class io_awaitable_promise_base
134			{
135			io_env const* env_ = nullptr;
136			mutable std::coroutine_handle<> cont_{std::noop_coroutine()};
137

139			/** Allocate a coroutine frame.
140
141			Uses the thread-local frame allocator set by run_async.
142			Falls back to default memory resource if not set.
143			Stores the allocator pointer at the end of each frame for
144			correct deallocation even when TLS changes. Uses memcpy
145			to avoid alignment requirements on the trailing pointer.
146			Bypasses virtual dispatch for the recycling allocator.
