v0.1.0

Main Changes

• Improve developer ergonomy:
  • Remove polymorphic allocator in favour of mimalloc
  • Change most pointers to references
• Compiler support expanded:
  • Support clang 14 and up
  • Support gcc 11.3 and up
• Implement co_await:
  • new AsyncGenerator class
  • Used in timers, RunFunctionEvent, http classes
• Improve CI pipeline
• Support added for configurable event queues
  • Multimap based
  • Sdevent based
  • User-defined ones
• Optionally use google abseil

Examples

co_await

Ichor now supports using co_await to wait on a response on HTTP requests:

auto toSendMsg = _serializationAdmin->serialize(PingMsg{_sequence});
HttpResponse &response = *co_await _connectionService->sendAsync(HttpMethod::post, "/ping", {}, std::move(toSendMsg)).begin();

if(response.status == HttpStatus::ok) {
    auto msg = _serializationAdmin->deserialize<PingMsg>(response.body);
    co_return msg;
} else {
    co_return std::unique_ptr<PingMsg>{};
}

For more example code, please look at the ping pong example.

Different queue implementations

To instantiate the Multimap based queue:

#include <ichor/event_queues/MultimapQueue.h>

using namespace Ichor;

int main(int argc, char *argv[]) {
    // ...
    auto queue = std::make_unique<MultimapQueue>();
    auto &dm = queue->createManager();
    // ...
}

And the sdevent based one:

#include <ichor/event_queues/SdeventQueue.h>

using namespace Ichor;

int main(int argc, char *argv[]) {
    // ...
    auto queue = std::make_unique<SdeventQueue>();
    auto &dm = queue->createManager();
    dm.store(&dm, std::memory_order_release);

    auto *loop = queue->createEventLoop();
   // ...
    queue->start(DoNotCaptureSigInt);

    int r = sd_event_loop(loop);
    // ...
}
