Detailed Description

Specialization for void return type.

Specialized version of PostAwaitable for functions that return void. Executes side-effect operations on the main thread.

co_await looper->awaitPost([]() -> void {
    // UI update or thread-safe operation
    std::cout << "Main thread operation completed" << std::endl;
});

Member Function Documentation

await_ready()

bool swt::PostAwaitable< void >::await_ready ( ) const

inlinenoexcept

Check if operation is ready (coroutine interface)

Returns

false - always suspend initially

Definition at line 385 of file Awaitable.h.

await_resume()

void swt::PostAwaitable< void >::await_resume ( ) const

inline

Resume coroutine after void operation completion.

Exceptions

std::exception

if operation failed

Definition at line 397 of file Awaitable.h.

await_suspend()

void swt::PostAwaitable< void >::await_suspend ( std::coroutine_handle<>  handle ) const

noexcept

Suspend coroutine and post to main thread.

Parameters

handle

Coroutine handle for resumption

Definition at line 326 of file SLLooper.cpp.

References SLLOOPER_DEBUG, SLLOOPER_ERROR, and SLLOOPER_ERROR_STREAM.

getFunc()

std::function< void()> swt::PostAwaitable< void >::getFunc ( ) const

inline

Get the main thread function.

Returns

Void function to execute

Definition at line 405 of file Awaitable.h.

getLooper()

std::shared_ptr< SLLooper > swt::PostAwaitable< void >::getLooper ( ) const

inline

Returns

Shared pointer to looper

Definition at line 411 of file Awaitable.h.

setException()

void swt::PostAwaitable< void >::setException ( std::exception_ptr  ex ) const
