executor.hpp File Reference

Executor abstraction — IExecutor (virtual), the Executor concept (duck-typed), and three concrete executors: InlineExecutor (runs on the calling thread), SingleThreadExecutor (owns a tiny thread pool of size 1), and ExecutorRef<Exec> (adapts a concept-conforming executor to IExecutor). More...

Classes
class	threadman::IExecutor
	Virtual interface for "anything that can run a `std::function<void()>`". More...
class	threadman::InlineExecutor
	Runs task() synchronously on the calling thread. More...
class	threadman::ExecutorRef< Exec >
	Wraps any Executor-conforming type behind the virtual IExecutor interface, so functions that take IExecutor& accept it. More...

Namespaces
namespace	threadman
namespace	threadman::detail

Concepts
concept	threadman::Executor
	Duck-typed alternative to IExecutor for templated code that wants to avoid a virtual call.

Functions
void	threadman::detail::execute_on (IExecutor &exec, std::function< void()> task)
	Dispatch helper used by Future::then / SharedFuture::then.

Detailed Description

Executor abstraction — IExecutor (virtual), the Executor concept (duck-typed), and three concrete executors: InlineExecutor (runs on the calling thread), SingleThreadExecutor (owns a tiny thread pool of size 1), and ExecutorRef<Exec> (adapts a concept-conforming executor to IExecutor).

Used by Future::then / SharedFuture::then to dispatch continuations and by callers that just need to enqueue some work without caring how it runs. ThreadPool itself derives from IExecutor.
