eve.core.windows.post

Post/defer callback management for the Windows event loop.

This module manages the defer and post callback queues used by the Windows event loop. Defer callbacks are thread-local and appended during a loop iteration. Post callbacks are thread-safe and drained into the defer queue on the next iteration.

struct PostState

Types 1

structPostState

Manages defer and post callback queues for the event loop.

The defer queue holds callbacks scheduled from the loop thread (via EventLoop.defer). The post queue holds callbacks scheduled from any thread (via EventLoop.post), protected by a mutex.

Fields

void delegate() @safe nothrow[] deferQueue

void delegate() @safe nothrow[] postQueue

Handle postHandle

Token postToken

Mutex postMutex

Methods

void defer(scope void delegate() @safe nothrow callback) @safe nothrowAppend a callback to the defer queue.

void drainDeferQueue() @trusted nothrowDrain and execute all pending defer callbacks.

void reset() @safe nothrow @nogcReset all post state for disposal.
