Boost asio get_executor
WebBoost.Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ … WebAn executor is to function execution as an allocator is to allocation. This proposal is the asynchronous model that underpins the P0112R0 Networking Library proposal, and the proposed wording below is taken from the corresponding sections of P0112R0. In doing so, it takes design concepts from Boost.Asio,
