Libstdexec Qt support

Why?

Cause

• Making it easier to compose asynchronous operations in a generic and efficient manner with Qt C++

Customer

• See separate listing from comments and/or Product Board

Cruft

• Still in standardization for C++ 26

What?

Definition

• C++ sender/receiver asynchronous programming model. Implementations for various asynchronous operations and algorithms, such as:

• • Schedulers
  • Timers
  • Asynchronous I/O (using Linux's io_uring)
  • Concurrency patterns
  • Async streams
  • Cancellation mechanisms
  • Coroutine integration

• See also https://github.com/NVIDIA/stdexec

Demarcation

• Implementation to Qt C++ only, not for any other languages

Dependencies

• NVidia's reference implementation, later the C++26 standard library, once implementations of these facilities are available as standard library components.
