An adaption of Senders/Receivers for async networking and I/O
This repository is still very experimental and in development. It's goal is to create abstractions for file and networking i/o using stdexec as a model for asynchronous operations.
The basic principles are:
- We use an
async_resourceconcept to asynchronously create and asynchronously release a resource- such a resource is usable via some copyable, non-owning token such as a
file_handleorsocket_handle - examples are files, sockets, schedulers, memory ...
- such a resource is usable via some copyable, non-owning token such as a
- We use sequence-senders for operations that could potentially complete multiple times
- completion are either sequential or in parallel
- examples are read and write operations, resolving hostnames or accepting new connections
This repository builds ontop of a specific branch of stdexec, namely the member-only-customization-points.
(see NVIDIA/stdexec#788)
Therefore you have to checkout the correct branch and install it such that CMake can find it.
To install stdexec in some <prefix> folder do something along the lines
$ git clone git@github.com:villevoutilainen/wg21_p2300_std_execution.git stdexec
$ git -w stdexec checkout member-only-customization-points
$ cmake -S stdexec -B stdexec-build -DCMAKE_INSTALL_PREFIX="<prefix>"
$ cmake --install stdexec-build
After having installed stdexec, you can specify the <prefix> folder to CMake via the stdexec_DIR variable as in
$ cmake -S senders-io -B senders-io-build -Dstdexec_DIR=<prefix>/lib/cmake/stdexec
This project has been tested with gcc-11 and clang-16.
