Investigate changing customisations of algorithms to be based on connect instead of invocation of algorithm itself

2

The current implementation of scheduler affinity for the coroutine `task` type relies on special behaviour of being able to identify when the coroutine awaits a sender returned by `schedule(some_scheduler)` so...

Add more type-erasing wrapper types

6

We currently have only two type-erasing wrapper types: * `any_unique` which always heap-allocates the wrapped object * `any_ref` which just holds a pointer/reference to a wrapped object and does not...

Rename is_stop_never_possible to is_stop_ever_possible

2

The usage of this query quite often ends up needing to be negated which ends up with a double negative (not is stop never possible) instead of the positive form...

Add Windows IOCP-based I/O executor

1

Implement a simple single-threaded event loop that uses Win32 IOCP to dispatch async I/O completion events so that we can build and run examples that do file I/O on the...

Change member-functions over to use tag_invoke

2

The paper [P2300R0](https://wg21.link/P2300R0) proposes having all CPOs used for senders be purely tag_invoke based and not dispatch to member functions. To be consistent with this, we should do a pass...

Add socket support to io_uring_context

2

Add support for tcp/ip sockets and udp/ip sockets using the io_uring_context event-loop.

Consistently catch exceptions thrown from set_value() calls

1

The requirement for `set_value()` implementations was relaxed to allow them to throw exceptions. However, this now means we need to audit all call-sites to `unifex::set_value()` to ensure that we catch...

Add Windows Thread Pool I/O scheduler

3

Add an implementation of an I/O scheduler that makes use of the Windows Thread Pool APIs to schedule work and handle I/O completion events. The current windows_thread_pool implementation supports scheduling...

Generalise coroutine task<T> type to support passing through receiver context queries to parent receiver/coroutine

1

We would ideally like to be able to define coroutine tasks that can pass through context from the caller to child coroutines to allow passing things like stop_token, current scheduler,...

Experiment with a low-latency Windows I/O scheduler

1

Implement some of the low-latency ideas from llfio's experiments with sender/receiver that allow I/O operations to complete prior to the completion event being posted to the IOCP queue by polling...
